Whenever this happens I have to log out, log back in again, and go back to the thread i was replying in. It’s really annoying and I’ve lost a post this way (Notepad is my friend, Notepad is my friend…) Is it a board glitch or something on my end?
Win Vista + Firefox 3.6 if it’s relevant.
Thanks for specifying your browser version number.
This is a reported bug in Firefox 3.6:

The only known solution at this time is to downgrade back to 3.5.7.

Thanks. 
I was considering that anyway as Facebook is giving me some strange behavior… definitely going to downgrade now.
