I have this most annoying problem with win 7 RC (built 7100), while surfing in internet explorer 8 stalls very often and I have to shut it down by using task manager, for some reason this problem appears usually in the beginning of session and sometimes it works just fine so it is hard to localize the cause for it.

yeah i had a similar problem too. so im using google chrome for now.. its better IMHO

Me too, bloody nuisance. If you open a second (or more) tab it sorts itself out. So how robust is it for the future? Worries me..!
