Ed? Who's Ed?

Can't say exactly which part of the forum it was. I was trying to respond to various threads I subscribe to, (Through email notification). But it has happened maybe 4 or 5 times in the past few days. When it happened, it effected every post I tried to respond to. What typically would happen is, I would get all the way to submitting a response and after clicking the button, the entire page turns white, and there's a short message in the very top left hand corner. Can't remember what it said though. If it happens again, I'll make a note of it.
