>>>I am having lots of trouble posting replies today. When I click Send, it just hangs there without actually sending the reply, even though it sometimes says Done. I have to exit Foxfire, then come back in. The first reply then works, but if I try to send a second reply it's the same problem. Is anyone else seeing this?

I've upgraded AVG too. BTW, are you using FF 3.5.5? I had problems with 3.5.4 which seem to be resolved with 3.5.5 (You can upgrade your system using Help/About, I think).
