Also notes other problems, including crashing Windows Live Mail

.....Ironically, of the nine applications called out as incompatible
with the new IE8, the only two that will lock up and crash are

Visual Studio .Net Version 7, said Microsoft, will crash on a PC that
also contains IE8 Beta 2. "No workaround is currently available,"
Microsoft said in the release notes.

The other Microsoft incompatible application is Windows Live Mail,
formerly called Windows Live Desktop, and the desktop mail client
meant to replace Outlook Express and Windows Mail. "If you install
Internet Explorer 8 Beta 2, Windows Live Mail will crash when you
create or reply to an e-mail message," Microsoft warned.
