      This is a display problem: go to "Options", select "Medium" (correct answer should appear), then select "Large" (again). Correct answer should remain, but with a slightly smaller font (than start-up) now. I recently upgraded to Windows 10, but honestly I don't remember how it behaved before.

    I have a bunch of key assignments that I make.
    To show them on the "keyboard" you can use a graphics program like Paint to add them to the relevant .bmp file in the program directory. There are three, small.bmp, medium.bmp and large.bmp . Remember to change the Properties on the Folder holding the program. Win7 has it as Read Only.
