Hi,

We are experiencing a problem with a windows forms control hosted in IE. 
Everytime I close the IE window we get this error:

---------------------------

..NET-BroadcastEventWindow.2.0.0.0.218f99c.0: iexplore.exe - Application Error

---------------------------

The exception unknown software exception (0xc0020001) occurred in the 
application at location 0x7c812a5b.


Click on OK to terminate the program

---------------------------

OK   

---------------------------

We have developed the control with .net framework 2.0.  We suppose that it 
is related to threading. Anyway if you know another cause please share it.

Hi Fernik,

I searched this problem in the Internet. Some resources I found said this 
problem is caused by the interoperation between managed and unmanaged code.

Could you tell me what the function of your WinForm control is and what the 
control does internally?

It's really hard for me to address a problem if I don't have a sample that 
could reproduce the problem on my side. 

If possible, would you please create a simple sample project that could 
just reproduce the problem and send it to me? To get my actual email 
address, remove 'online' from my displayed email address.

Thank you for your understanding and cooperation!

Sincerely,
Linda Liu

Hi Fernik,

I found a  post that produces almost the same exception as your WinForm 
control. A workaround is also provided in that post.

You may refer to it through the following link:

Hope this helps.
