Too many clicks

[Greg Wills]

Hi All
Hope the new year is being good to you so far.

I'm having difficulty locating the correct term to stop multiple 
clicks before a script is run.

In a dice type game, students are to click on a button to roll the 
dice. Some students are clicking on the button more than once and 
this is causing multiple rolling of the dice. Can anyone suggest the 
term/script to lock out any further clicks until the next click is 
needed - after a sub stack is shown, answered and then return to the 
main stack.

regards
Greg
