Powerpoint and Smarboard help

I have a presentation/game that runs fine without my smartboard but will only
run fine at times when I connect the smartboard (e.g., sometimes it works and
sometimes not). It's a very simple game where the player just touches a
picture that they believe is the correct answer. The game does involve a
running clock which is what I believe is causing the problem, but have no
clue as how to fix. If the clock is not running the game will work with the
smartboard, but if I start the clock (i.e., countdown) the game will only
work some of the times. Just wondering if anyone has had a similiar issue
and could help. I'm at home now so I don't have any code, but will gladly
post tomorrow if needed.
