Thanks for the speedy reply!
I have all of the shortcuts in the software preferences menu set not to be used, and only have the F1-F11 keys and ESC key set to display individual pages as shown in the photo below.
The F10 issue I am having seems to be a Windows-default key for most programs, where it will set focus to the main menu bar when pressed. It doesn't seem as if it can be set in CompuShow's shortcuts menu.
Do you know if there is a setting in Windows which disables this key's default action, or do you think it is programmed directly into CompuShow?
Thanks,
BV
