App crash due to MSHTML on win 7 x 64

Hi All,

I have a .Net 1.1 application running on Win 7 (64 bit) and Internet
Explorer 8. This application uses MSHTML editor control for editing
and viewing HTML documents.

Application is crashing (very frequently) when HTML editor is loaded
for first time by the application. When I restart my application and
load HTML editor again, it generally works fine. I never faced this
issue with WinXP.

Error details in Windows Error Report file are given below. Please
also let me know how such an issue can be debugged if it only happens
at customer end.
