As I said, keep this on topic, there's no need to discuss what browser is better or not. If you want to discuss that go to the Non BB folders or discuss via BB Mail. This certainly doesn't belong in the help forums.
Buzzerbeater should indeed be compitable with all browsers, and the BBs are working on the problem.
BB-Forrest already mentioned he made a fix for this problem in the new site.
(106628.10).
Please let him know there if it's fixed now or not, and once again this is no place to discuss wether microsoft is good or not.
