Sort of.
Graphic Buttons *only* work on PalmOS 3.5 and later. They don't even exist on earlier
releases. If you try to open a form that contains them, the OS interprets the bitmap
IDs as a pointer to a string, and tries to follow the pointer. Depending on your IDs,
you could get a bus error or you could get random memory junk.
Don't use new APIs on old OS's!
