I tried per application in windowblind settings to not skin ie9, but it still crashes.
IE9 is a just-out beta...so there is going to be a bit of 'chase up' involved.
I expect that if IE is still crashing with the exclusion set...there's some component of the EI proggy still not 'excluded'...either that or some horrid tie-in with another process [like explorer.exe].
Neil will be sure to catch up with this...but please provide specifics...OS ver [eg 32/64] etc will be essential...
