Experts, please advice.

I have a WPF application developed using Visual Studio 2008 + DotNET 3.5.We have wrapped Our WPF application in Active X and hosting in IE 6 and it is works fine ,recently we migrated to IE 8 .Actually we are launching our app inside a parent application
which is Browser based application(developed in java).

When we launch our app in IE 8 and switching between different modules along with our app in parent application our application is crashing.Pls find below stack trace for the problem.

Thanks,

Hello,Based on the info at hand it appears that there had been a problem a while ago and this generic stack trace does not provide enough information to even guess the issue.In checking with colleagues here My recommendation would be to have you open a paid support incident with Microsoft support, and seeif we can’t get a repro. You may have a few options for opening said support incident or advisory.Alliance and Premier VSIP membership includes a complimentary MSDN subscription, which includes 4professional support incidents. These can be used to initialize a support request with Microsoft’sCustomer Support Services. Some versions of Visual Studio include a number of free support incidentsas well. See the “Technical Support Incidents” topic for details.

Bill,    Thanks for your input and we will open a technical incident with microsoft.Yes, i agree stack trace might be confusing but i still wonder what could be the reason
