User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3) Gecko/20030312
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3) Gecko/20030312

Windows XP Pro, build 2600.xpsp1.020828-1920

While using mozilla, I accidentally pressed Windows key + U, which brought up
the Utility Manager in XP and a voice began reading the contents of the foremost
window. I clicked on the link titled "Microsoft Web site" in the Microsoft
Narrator window that came up, which began loading www.microsoft.com/enable/. I
went back to the Microsoft Narrator window and clicked OK to close it. After
closing the Utility Manager, I went back to Mozilla & she was hung. I have
stacks from several crashes that I will attach, all reproduced by following the
same steps below.

Reproducible: Always

Steps to Reproduce:
1) open mozilla
2) press Windows key+U (brings up Utility Manager)
3) listen to Microsoft Sam
4) in the "Microsoft Narrator" window, click the link titled "Microsoft Web
site" (sometimes it hangs here)
5) www.microsoft.com/enable/ will load in mozilla
6) go back to the Microsoft Narrator window and click OK to close
7) (normally I've noticed mozilla's already hung at this point) click Voice...
8) click Cancel
9) click Exit
10) click OK on the Utility Manager
11) go back to Mozilla...oh yeah, she's hung :(
Actual Results:  
Mozilla was hung, had to be force-closed...talkback does not kick in.

Expected Results:  
Mozilla should not have frozen. :)

This is causing firebird to hang w/ 99-100% CPU throttling. Using TCPView,
showing that she's still opening/listening/closing/etc. connections while hung.

I have to End Task her. Will attach the exception analysis from the minidump
created when I killed her.
