Thanks alot for your effort higorion, but unfortunately this didn't help at all.
I replaced the addEventListeners as yot told me to and pasted your code, but I got just the same error as before. I removed all listeners, and that seemed to stop IE from crashing, so it seems clear that it's the events that are causing the trouble. I tried to put an alert at the top of your exit() function, but never got an alert on refresh, so the browser seems to crash before even running the exit() function. Hmmmm.
