Don,
I must apologize. It's a false alarm.
After rechecking the problem, now I discover the culprit — my Macro Scheduler.
I wrote a Macro Scheduler script to alter the behavor of F10 for all apps including XY, CorelDraw, Word, Excel,...etc.
Yes, the "factory default" F10 and F12 works fine as advertised.
Don, appreciate your help.
