Microsoft: Windows Live Mail works fine with IE8 Beta 2
Mistake in Internet Explorer release notes now corrected.
Microsoft last week said that it made a mistake when it tagged one of its own programs as incompatible with Internet Explorer 8.0 Beta 2.

In the release notes that accompanied Internet Explorer 8.0 Beta 2, Microsoft initially listed Windows Live Mail as problematic on PCs running the new browser.

"If you install Internet Explorer 8 Beta 2, Windows Live Mail will crash when you create or reply to an email message," Microsoft warned in the release notes.
