Intellij 5.0 hangs

Hi,

I've download?? idea 5.0 a couple of days ago and started testing it, feature wise its cool, however about every 5 to 10 minutes it hangs, gets stuck and I have to kill the process and restart it.

I'm using multiple module files and integrate with ant files, nothing too complicated, I did things like this in IntelliJ 4.5 (not the same projects).

I still dont have the exact situation\time\operation on which it freezes, but its very disturbing, I am already considering going back to 4.5

Thanks,
Asher
