You can paste if you use 'ctrl v' Copy like regular then click in the reply box where you want to paste your stuff and press ctrl plus the 'v' key. It should paste.
Good tip and it works. I've also noticed than when you attempt to add a quote later in a post, it deletes everything else in the post during the "reloading" process. Not a good thing and annoying.
Sven, I'm using Norton Internet Security and mozilla also. When they first amde the change, I couldn't stay logged in or post because of a cookie issue. I followed admin's directions on clearing the cookie cache and restarting. It worked fine and my firewall is still turned on. I have mine set at medium security. Is yours set at the highest level? Perhaps that's why it was causing you problems.
p.s. I forgot to mention that Norton has a new spyware addition to Internet Security and they are selling it for $10 to existing customers (versus $60 something for new buyers). I'm waiting to recive mine and hope it clears up a few more of the adware/spyware probelms.
