Try using a different user profile. There may be something stuck in your temporary internet files or in some browser helper object causing IE to crash. I have seen this before and done the following to get by the problem:
Login as local admin on the workstation
Rename the problem profile to something else
Logout from the admin account
Login as the user and a new profile is created
Try the browser and see if that fixes the problem
If it does not fix the problem, then you may have some corrupted files or possibly even a virus of some type. I would suggest you talk to your internal IT support staff for additional support on this issue. If you are the IT support staff. Then please post more information on this board for additional assistance.
