try
Did you try another software?Can you an manually enter a quickey assignment for a conventional system above the 10?If you can not I would reset the scanner to default and rehit it with your programming.I've had things get "jumbled" up on the 396/996XT ,its easy to rectify.
Forgot to ask,have you done anything new to your scanner or computer lately?
Note : Microsoft .net framework is pretty much junk! I would remove that and reinstall it if all else fails.
Ive also had issues where that craps up and the home patrol software didnt work right.
freescan requires .net software to work!
