  • why AfxWinMain is not on the call stack? are you running automation code from a background thread?

  • It is a secondary UI thread, and in its window it has a web browser control.

  • Hi,

    Thank you for posting here.

    Could you please tell me which version of IE are you using? Can you test on a system with a newer version of IE? According to your issue, I suggest you could post the issue on the Internet Explorer Web Development for better support. 

    Best Regards,
