Sorry, but you're being way too vague for us to help you. Next time the error appears, please write it down/take a screenshot and give us the full error message here. What do you mean by you "can't see anything except your toolbar"? Which version of Windows are you using? Which version of IE (I'm speculating you're using IE, but I'm probably right)?
Initial thought leads me to think that this is IE's fault, but I can't be sure until I get some more information.
