Acrobat Reader 8, 9 crashes on Vista, XP, 2003 server by following steps:
1. Open two huge documents (>1000 pages).
2. Get IAccessible object by AccessibleObjectFromWindow function from external application.
3. Fast scroll in one document and quickly click on second doc's vertical slider bar several times.
Here I get APPCRASH ("Acrobat Reader has stopped working").

If external program doesn't get IAccessible, Acrobat Reader works normally.
If I close external program after getting IAccessible Acrobat crashes after scrolling too.

Reading mode option is set to "Read the currently visible pages only" in "Accessibility Reader Options".

any ideas?
