Ok, I solved my own problem...
I added a global variable called "LoopBusy" and set it to a "0".
Then, I added an additional condition to my Collision loop
if LoopBusy=0 then execute. My first instruction in this Collision
loop is to set the LoopBusy variable to a "1" and then reset it back
to a "0" at the end.
Because C2 is more of a visual environment, I have had some troubles finding where everything is...
