Oops! I should have thought better before asking...
In this case my best (and fastest) shot is to back up Mariano's suggestion, it is VERY unlikely that the same happens with a different browser.
Of course, if I was Microsoft, I would first suggest that you may have missed some patch - but I'm not

.
At this stage, even if there was a site application error involved (could be some JavaScript problem), it's treated so "unfriendly" that I doubt anyone could find it by the "report" provided by IE. By the other hand, it's likely that another browser reports such an error more accurately.
A more elaborate solution would be to enable JavaScript error logging in the IE, with the hope that an error could be raised before that very fatal crash. This error could help further investigation...
Sorry I could not be of much help. Besides, not flying the F1 event myself, I cannot test to see whether I get the same "result".
Cheers
