VB.NET Program Locks Up with Internet Explorer Opened

I'm using Visual Studio 2008 and developing a VB.NET application.
I'm having strange lockup problems with my program, but only when Internet explorer 8 is opened.

When I cover my form with another window and then uncover it, I find that it has locked up.
My program has no references to IE and the only thing it even has to do with IE is using Process.Start with a web address.

My program works fine and exactly as it should, but only when IE is not opened.

Does anyone know why a program would lock up only while IE is running?

Edit: I've done some digging and I've found the offending thread in my program.
I don't know what starts this thread or what it does, but when I kill it, my program no longer freezes. The thread is one of the CreateApplicationContext threads, here is the last few items in the stack trace of that thread.

Process explorer says my program is using no CPU nor throwing any exceptions while it is hung.
