Edit box messed up when posting/editing msg

I have Firefox 3.6 on Win XP. I get on this forum almost every day. Today when I post or edit a message, the buttons for Save, Go Advanced, Delete and Cancel are overlapping the text edit box where I type my message. FF has always worked with this site. Has there been an upgrade that affected any parts of the forum software? A library updated perhaps?

I'll restart FF and see what happens.

Interesting. Restarting Firefox fixed the problem.
