Lost Post?

I was in the middle of replying to a post, and was called away from my desk. Came back, added a bunch to the post and submitted. I received a you are not logged in message, even though the post page showed that I was indeed logged in as PhotoHutch.

I logged in, and everything was gone, nothing left but an empty message box waiting for words.

Is the post lost forever? Is there a time limit for inactivity?

Thanks!

Thanks for the tip on keep me logged in. I figured that was a cookie sort of thing. . . .

No big deal, probably for the best. My post was a somewhat snippy reply to a slightly condescending comment. . . .
