Hi,
I'm reposting your image here:
My best guess is that there is some javascript problem going on. We use NeatHtml in the forums to protect against cross site scripting and my best guess is there is some compatibility problem with NeatHtml and the mobile version of IE. I will email Dean Brettle, the author of NeatHtml to bring this to his attention. I'm not sure he has a way to test this browser though unless there is some simulator that can be used.
Best,
Joe
