While you complain about this issue, you posted in the wrong forum!
That said, while the forums are slow on some days, and if NOT logged in, and I want to reply, logging in, gives me a wrong page error. I just have to hit back a couple times, and since the cookie is now there, it works... It's not a browser issue, it's you.
Other than that, the forum works for me more than 90% of the time.
BTW, this is not a true support tool, Support is. This is a community based website where we try to help you. We just happen to have some Symantec employees that troll around from time to time here.
