hello, I recently had the same problem you did with I.E 6.0 for some reason it just shuts down. I solved the problem by reinstalling Internet Explorer, it worked just fine.

Someitmes the problem can also be related to a pop up blocker you may have.

Hope I helped.

I tried uninstalling the google-toolbar - which had a popup blocker and tried sending a big email thru yahoo - again got the same message - it says "IE has encountered a problem and needs to close"....it trys to send some report to msn support.

First we had IE5.5 - when this problem started 3-4 days back we installed IE 6.0 yest
and the problem still exists. Before everything was fine - somebody has got anymore tips let me know....

what I mean is go to add remove programs and completely uninstall internet explorer.

I was going to suggest a ie repair ,i think you can do it in add/remove programs .add/remove windows components , unchek ie and i think you will be giving the option to repair it .
