I can log in to Hotmail with Safari or Firefox, but not into the Windows Live version. I'm told that I am "temporarily" using the classic version. I should log off, clear the cache, and clear cookies before logging back in. Doing those things has no effect - I'm still confined to the classic version afterwards.
Internet Explorer on the Boot Camp partition works fine.
Not much of a deal because I don't rely much on the account, but it would be nice to get this to stop.
