Known Problems for Mobel on Apple Devices

All versions
Some users report that Mobel's rhythm is not steady on iPhone 14 and 15 (though it is fine on all other devices). Version 2.3.7 has improved this for some of these users. Further reports would be welcome; please email (see above) if this affects you.

Version 2.3.7
There are no known problems in version 2.3.7.

Version 2.3.6
The orientation lock stopped working on devices with iOS 16, due to a change made by Apple. Since all modern iPhones/iPads allow the orientation to be locked in the device settings, the lock is no longer needed in Mobel, and is removed in version 2.3.7.

Version 2.3.5
An obscure problem, present in this and all previous versions of Mobel, affected a small number of users. It is fixed in version 2.3.6.

Version 2.3.3.and 2.3.4

Version 2.3.1
When ringing handbells, if a user touched and held one bell, then touched the other, the latter didn't ring. Fixed in version 2.3.2.
A user found yet another way of creating an invalid composition that caused problems for Mobel. Fixed in 2.3.2.

Version 2.3
There was a compatibility issue for those who used Block or Differential methods in previous versions of Mobel, then upgraded to version 2.3. Fixed in 2.3.1.
When using WaitForMe, if a user hesitated when leading, call prompts could be omitted. Fixed in version 2.3.2.

Version 2.0 to 2.2.7
People found various ways to make Mobel crash by adding invalid methods or compositions, or by doing strange things with the peal time. There were also a few other rarely-encountered issues. All of these are fixed in Mobel 2.3.

Version 1.0 to 1.3
Various small bugs got fixed in the next version.

Known Problems for Abel on Windows PCs

Versions of Abel from 3.9.2 onwards require Pentium IV processors or later (any x86-compatible processor made this century!). If you have a very old PC with a Pentium III processor, contact the support address (above) for assistance.

If you use Handbell Manager with Abel 3.9.2 or later, you need to update to the latest version of HM. See the Handbell Manager section of the Downloads page for details.

Version 10.3.2
There are no known problems in this version of Abel.

Version 10.3.1
In the striking view, if you use keyboard up/down to scroll the view, the blue/grey lines are not drawn correctly. Fixed in Abel 10.3.2.

Version 10.3
In this and earlier versions of Abel, intermittent problems occured when changing Options>ExtBells. This is fixed in version 10.3.1. A minor bug when using extreme bad striking settings is also fixed in 10.3.1.

Versions 3.10.2 to 3.10.2b
It was possible for Abel to get into a state where it wouldn't load; this happened rarely on Windows 10, but more commonly on Windows 11. This is fixed in version 10.3.

The striking display had a minor bug when using Moving Ringers from the keyboard, with User Starts Bell Movement turned on. This is fixed in version 10.3.

Key up/down ringing didn't work in 3.10.2. It's fixed in version 3.10.2a.

High resolution screens. With any Abel version before 10.3 (March 2022), on high resolution (4K) screens, Abel's blue line display, and some other text, may appear very small. To correct this, right click the Abel icon on screen, then click
Properties > Compatibility > Change High DPI Settings
then click High DPI Scaling Override, and select "System" from the associated dropdown box. (These instructions are for Windows 10; other versions of Windows should be similar.)

Version 3.10 and 3.10.1
A few users of Abel 3.10.1 found that Abel's toolbar disappeared, and wouldn't come back. This is fixed in Abel 3.10.1a. There are no other known problems with Abel 3.10.

Version 3.9.2

When ringing up with Abel, sometimes bells do not start to sound the backstrokes. If this occurs, you can correct it after the ringing up by clicking Reset (or press F4). You can avoid the problem: immediately after you have started Abel you should pull one of the sallies and allow it to swing at backstroke. If anyone first pulls a sally and stops it without allowing the backstroke swing, click the Reset button (or press F4) then pull a sally and allow the backstroke swing. The bells will then ring up correctly.

Version 3.9
If you increased the number of bells by at least two, then rang a bell before clicking Start, you got an error message, and sometimes strange behaviour afterwards. Fixed in version 3.9.0a.

The CAS striking analyser requires upper case letters for bells 11, 12 etc (ie, E, T), but Abel 3.9 used lower case. Fixed in version 3.9.0b.

In the Learning Exercises method collection, there was an error in the 3-4 Long Places exercise. Fixed in version 3.9.0a.

If you opened a saved striking file, then tried to save in Lowndes format, the save failed. Fixed in version 3.9.1.

Version 3.8 and 3.9
On some older PCs, typically running Windows XP, there may be white flashes on screen when using the Moving Ringers display. This is probably due to a slow graphics card and/or a slow processor. It may be improved if you run Abel immediately after turning on the PC (so that little else is running); if you avoid having the mouse cursor pointing to the toolbar (which makes Windows use lots of processor power looking for clicks); and if you set Abel's Options>Screen to "Long bell pictures shown in a line", though this is regretable since it is less realistic than having the pictures in a crescent.

Versions 3.0 to 3.7
Very few problems were ever reported in these versions. If you do encounter a problem, please update to the latest Abel version that will run on your PC.

Windows Vista/7/8/8.1/10 with old versions of Abel
If you are using Windows Vista/7/8/8.1/10 with Abel 3.5.3b or earlier versions, you may find that Abel's help system doesn't work, or that you can't save changes to method collections, option files, etc. These issues were fixed in version 3.6.

Installing old CDs
If you have a very old Abel CD, you may find that it will not install on a modern PC (because the PC will not read the CD, or because of an installer problem). Email AbelSim at the address given above to request a free download of the current version of Abel.

Known Problems for Mabel on Apple Mac

Apple warned in late 2018 that older apps, such as Mabel 1.0.2, would not run on future versions of macOS. Users of Mabel 1.0.2 must upgrade to a later version, to continue running on macOS 10.15 (Catalina) and later versions.

Version 1.1.1

There are no known problems in Mabel 1.1.1.

Version 1.1.0

When running on MacOS 14 Sonoma, prompts during ringing (eg, bobs and method names and call changes), and the striking information, did not display correctly. This is fixed in version 1.1.1.

Version 1.0.2

As in version 1.0, if you press the space bar at the start of a change, strange things may happen to the blue line display. It only seems to happen on some Macs, and with some versions of OS X. If this happens on your Mac, do not use the space bar as the key for ringing a bell or making a call.

Version 1.0

If you press the space bar at the start of a change, strange things may happen to the blue line display. It only seems to happen on some Macs, and with some versions of OS X. If this happens on your Mac, do not use the space bar as the key for ringing a bell or making a call.

For users with Mac OS X 10.7 (Lion) only, there is a problem with opening method collections. When you click File>Open on the menu bar, the dialog that appears may not show the available method collections. It seems that Apple have introduced an incompatibility, or even a bug, in Lion. This is fixed in Mabel version 1.0.2 (see the download page).

There is a problem if you try to add a Treble Place method from the microSIRIL library. This is fixed in version 1.0.2. Users of Mabel 1.0 with MAC OS X 10.6 (Snow Leopard) or later can upgrade to version 1.0.2 (see the download page).

For users with Mac OS X 10.4 (Tiger) only, there is a problem with adding and editing call change compositions.
