hm. with firefox and the latest flash notification everythin runs fine. but with win7 and ie8 and probably the latest flash (installed several times from adobe homepage) it freezes sometimes.
some minutes ago i watched a match which worked fine in ie8. i tried to watch two more games but there was the freeze but just in both games, not in the one i was watching.
with firefox everything works and i can watch more than one game at a time.
i just didn't find solutions while reading the forums..
p.s. i'm using www.buzzerbeater.com
