Replacing AVDocClose causes I.E. 9 to crash

Question

Hi guys,
I just wanted to bring this to everyone's attention in case someone else runs into the issue. My Reader enabled 10 and Acrobat 10 Core API plugins are causing I.E. 9 to crash. The customer browses to a web page that contains links to pdf documents. They click the links and the pdf's are opened in a new tab in I.E. After reading the document, they click the X on the tab. As soon as the tab closes, I.E. crashes.
I've reproduced this issue and found that the cause is the AVDocClose replacement. Using a basic plugin with no business logic that replaces AVDocClose causes a crash.
I'm going to try to work around this using the AVDocDidClose event instead of AVDocClose.
Thanks,
Howie

Follow up:
I ended up having to use AVDocWillClose event instead of AVDocDidClose event. All I need is the path of the document being closed so that I can notify my program which file was closed. Unfortunately I get an  exception in the AVDocDidClose event when I try and get the document path from the AVDoc that is passed in.
ASFile pdffile = PDDocGetFile (AVDocGetPDDoc(doc));
ASPathName myname = ASFileAcquirePathName(pdffile);
CString strDocPath = ASFileSysDisplayStringFromPath(NULL, myname);
The exception is raised when ASFileSysDisplayStringFromPath() is called. These same lines of code work with the AVDocClose replacement and the AVDocWillClose event.
