Joe, thanks for the info!

Okay, related to interrupts, I've run into another problem. I go into my interrupt routine, detect a button on a port change and then tell the program to resume at a new routine based on which button was pressed. The first button works fine, but whenever I press the second button, it seems to ignore/skip the resume (colored below) and go on to the end of the interrupt routine. I added a toggle to an LED to indicate where the program was going. It works before the colored resume statement and after the end if statement, but not immediately after the resume statement. I also tried it at the beginning of the Score_player2 routine, which of course didn't work. I tried a quick search on the forum, but didn't come across anything similar, at least not yet. Any reason PBP would skip or ignore a resume statement? I've just included the interrupt routine - the rest is very similar to the code posted above.

I don't know if this is an indication of another problem, but I'm multiplexing two seven segment digits and whenever I press either button, one of the digits goes out, sometimes digit A and sometimes digit B regardless of the button pressed, and comes back on whenever I release the button.
