Then when 3 seconds elapse check the global variable before submitting 
if the global is less then 3 seconds old don't submit.

That sounds good, but my Javascript is very weak. Any code snips would 
be very helpful.

Yes, they do. The right frame may not always contain the same code. I 
think even if I copuld do it this way I might be doinf a lot of 
unneccessary submits.
