Problems with IE Browser Control when Adobe Acrobat Reader plugin is active

P: n/a
I have the following problem:

My client application (c#, WindowsForms) uses the IE Browser ActiveX
Control to display either HTML or PDF files. This is fine so far. If
the Acrobat Reader is configuered appropriately, the pdf-Files are
displayed right in that Browser Control.

Only problem is, when closing the Application there is a memory access
violation. It occurs outside of my application, only when its Thread
is just about to finish. It seems that either the IE Control
(AxWebBrowser) will not end the Acrobat plugin correctly or that the
plugin itself won't release the resources.

Note that our control is inherited from AxWebBrowser (but does not
overwrite any crucial methods). Also, when used with Adobe Acrobat
Reader 6.0 instead of 5.0, a message from the Reader appears that
there are still open Documents and if you are willing to lose its
contents. If you accept, the described problem will occur with a
probability of about 5%, if not - 100%. THIS MESSAGE APPEARS BEFORE

Does anybody have had similar problems or can help me somehow?

Any hint is appreciated.

Thanks, Phil.
