CF doesn't know it's a code tag so it probably thinks you're doing some sort of buffer overflow attack LOL.
I've had similar problems trying to send stuff via PM.
Edit: after some experimenting it looks like it doesn't like the word "Sleep". I removed three occurrences of "Sleep" from that function and it went through.
Edit 2: Actually just the first one is a problem - the "Sleep" and "(50);" (I can't even quote this line here - CF blocks it) ~10 lines from the top. Removing one letter allowed it to be posted.
Some experiments outside code tags:
Sleep(50); // this goes through
"Sleep();" // this goes through
"Slee(50);" // blows up if I add the "p"
"Slee(5);" // blows up if I add the "p"
"Slee(4);" // blows up if I add the "p"
'Slee (12345);' // blows up if I add the "p"
So quotes + an argument to the Sleep function blows it up. Perhaps any character preceding Sleep is a problem. So I just removed all leading spaces on that line and it went through:
