But they aren't I suspect some sort of conflict with Opera, which I'm using instead of IE, although I still can't log in even if I never start Opera. hmmmm.

Anyone have any suggestions? Can't find anything useful on their website- anyone have similar problems?

could be opera is already logged on or something...

for how long have you been having this problem?

what do u get when u try loggin into yahoo from opera?

my suggestion is u wait for the session to expire(maybe 30 to 60 mins)....
