Timed User Input

[Rick Harrison]

I'm trying to set up a guessing game where
the user has to race against a timer to give
an answer before the time runs out.

The problem is that when the user is asked
for input, the timer stops due to the interrupt.
Or the timer keeps running, and doesn't allow
any user input.

To work correctly the timer should still be
counting down as the user is trying to
answer the question.

Any thoughts, ideas, or suggestions are
greatly appreciated.

Thanks,

Rick
