Steps to recreate issue:
1. With Adobe Reader 9 loaded on your Windows PC...
2. With ANY browser, go to any url where you can download PDF forms (ex. www.dlis.dla.mil/PDFs/DD2875.pdf OR http://www.irs.gov/app/picklist/list/formsInstructions.html and click on any .pdf form)
Results: The browser (whether IE 6, 7, 8 or Firefox, Netscape, etc) will crash. The support window takes you to a place that informs you it is an Adobe problem.
Expected results: The PDF should be opened and displayed as usual.
Mitigation: It only occurs with Adobe Reader 9. When I uninstalled Adobe Reader 9, and reinstalled 8.1.3 there was no issue.
Can I get a witness?
How about a fix for this?
[I also work at government sites where they have lots of .pdfs accessible online. They cannot open any of them because of this issue with Adobe Reader 9; the browser just crashes and that is the end of that.]

However, sometimes replacing \windows\system32\ace.dll with the adobe one in \program files\adobe ...... reader\ace.dll has been said to work. Really ugly fix - hopefully someone at Adobe corrects this issue in the future.
