If you cannot find out how to do something even after studying the Help documentation - or simply want to share your experiences - please send an email to the address given above.
If you are having problems with Abel/Mabel/Mobel, please look through the known problems below and also look at the troubleshooting section of the Abel/Mabel documentation before contacting us for help.
If you've got a problem and you're not using the latest version of Abel/Mabel, download and install the latest version: the problem may already be fixed! For Mobel, download the latest update from the App Store or Google Play store. (For the Play store, start the app, tap the menu button (three horizontal bars), then select My Apps & Games.)
There was an obscure crash, that could happen if you stopped using Mobel when it was in the Methods page, then came back to it some time later. This is fixed in version 1.0c.
There was a problem with the Handstroke Gap switch on the Settings page. Also, Mobel would crash if you showed the blue line for a method that had bobs defined but not singles; and there were a couple of more obscure crashes. These were all fixed in version 1.0b.
Version 2.0 to 2.2.6
People found various ways to make Mobel crash by adding invalid methods or compositions, or by doing strange things with the peal time. All of these are fixed in Mobel 2.2.7.
There is a small compatibility issue on iOS 8. When you first tap the i button to change Mobel's settings, the current settings for Stage/Composition/Method/PealTime are not shown. If you rotate the device, they will appear! This is fixed in version 1.3.
Due to device limitations, the rhythm of the ringing may be very slightly unsteady at some ringing speeds. If you notice that the rhythm is unsteady, change the ringing speed (peal time) up or down by 2 or 4 minutes, and the problem will disappear.
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 3.10, you need to update to the latest version of HM. See the Handbell Manager section of the Downloads page for details.
Version 3.10.2 Key up/down ringing didn't work. It's fixed in version 3.10.2a.
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.
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.
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.
Apple warned in late 2018 that older apps, such as Mabel 1.0.2, would not run on future versions of macOS. Users running macOS 10.7 (Lion) or later should upgrade to Mabel 1.1.0 to to continue running on macOS 10.15 (Catalina) and later versions.
There are no known problems in Mabel 1.1.0.
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.

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.
