Quote Reply feature not working

[sayhello]

I've tried to reply to a post on 2 different computers, and both times, when I hit the "Quote" button, the reply window comes up, but there's no quoted text. Just a blank text area. Both are using Firefox, if that makes any difference. It worked yesterday.

Sayhello

PS, it works on IE.

Aaand it appears to be working on Firefox again...
