Yeah, it indeed stops while loading Slayer.
But it doesn't give any information as to why the crash happens.
I think it is better if Greek2me takes a look at this.
He lurks around on the help section, so it is probably just a matter of time before he sees this.
But you could always PM him if he doesn't respond in a day.
In the meantime, could you open the console and type "trace(1);" before the crash happens?
It then logs everything that happens in the console.log, which should give a better view of the problem.
