mshtml.dll error when running ASP.NET application

[Florin M]

I am running a custom application developed with ASP.NET 1.1, C# and Visual
Studio 2003.

I recently installed SP2 for XP Professional.

When I close the Internet Explorer window where the app runs, Internet
Explorer crashes and I get the generic error message window with DEBUG, SEND
ERROR REPORT & DON'T SEND buttons.

I checked the event log and the error item I found has the following message:

================================================
Faulting application iexplore.exe, version 6.0.2900.2180, faulting module
mshtml.dll, version 6.0.2900.2523, fault address 0x00058300.

I would appreciate very much your input!

Thanks,
