Aw man, less than 5 minutes and it's crashed already.  Sad

EDIT:  It crashes everytime I close a tab.

Unhandled exception at 0x68767939 in iexplore.exe: 0xC0000005: Access violation writing location 0x00000004.

EDIT2:  Hmm, restarted IE9 and now it's not crashing. 

EDIT3:  After logging into Channel9 and posting, then opening a new tab, and closing it, it crashes again.  Coffeehouse forum open in the first tab, and anything else in the second tab, it seems, but only when logged into Live.

EDIT4:  Nothing to do with signing in ... it's just not 100% consistently happening, but is happening most of the time (7/10 times, roughly).

EDIT5:  I think it's one of the addins from the beta.  Disabling them all.

EDIT6:  10/10 tries with add-ons disabled and no more crashes.  So that's good.
