I've noticed in iChat that opening a chat connection to some, but not all, of my Windows using friends, iChat suddenly decides to consume all unused processor cycles. Since I have a laptop which frequently is being used on my lap, this makes the laptop get much hotter than necessary. The only way to get it under control again is to quit and relaunch iChat.
Why is my computer trying to scorch me?!?
