Acrobat crashes in minimal WebBrowser control

[Don Shmon]

Hi,

We have an application hosting the WebBrowser control and we have some very large enterprise customers who use it to view PDF files.

They have been running into a very consistent crash in PDF reader but only when full Acrobat is installed.

I created a very minimal WebBrowser control application and I can reproduce this crash, but I can't tell why Acrobat is crashing.  The crash always happens in RtlEnterCriticalSection as it is called from Acrobat.dll.

We have multiple dump files (although they all look the same).

Can I get someone from Adobe to help us debug this issue?

Would it be possible to get debug symbols for the Acrobat.dll to get a better idea of what might be happening so we can try to find a workaround?

We did find that if we left a pop-up open with Acrobat loaded then the crash would not happen in subsequent pop-ups, so we were pursuing that as a workaround, but we then found that the workaround doesn't work if the pop-ups are loaded in their own threads (which we do sometimes because this is more like IE).

Anyhow, we are kinda stuck and so are our enterprise customers, so we could really use some help from an Adobe dev.

Thanks!
