Flash Circle TD Question
 

Got a quick question for you guys. In the Flash Circle TD game at Candystand.com, every time I get to level 75ish (sometimes sooner, sometimes later), the enemies just start disappearing. Problem is, they don't deduct from the total enemies count...so when the next wave hits, I'm screwed.

It seems as it's a memory issue as the game seems to be going REALLY slowly by this point. What I don't understand, is that I'm playing on a brand new Dell laptop with plenty of memory. Any advice on how to keep the game moving at a decent pace, or has anyone else experienced this?

Thanks for the help guys!
