Threads disappearing from forums on various browsers

Hi:

I've noticed that when I reply to a thread, that thread disappears from the forum in which it was previously visible. I'm not sure whether it happens every time, but the last two times I've replied to a question on the After Effects forum that thread disappeared from the forum, at least on my browsers.

For instance, I read this question today on the AE forum:

http://forums.creativecow.net/thread/2/1051826

I signed in, composed and submitted my reply, but when I went back to the list of threads this one was no longer visible. This is on Safari on a Mac running 10.7.5.

I launched Chrome, went to the AE forum, and this thread was visible. I noticed a typo; I logged into Creative Cow, edited my post, but when I went back to the forum the thread disappeared on Chrome, too.

And as another test, I launched Firefox and navigated to the AE forum on CC. This thread was visible. I signed into Creative Cow, went back to the AE forum, and the thread was no longer visible.

Am I missing a preference or something that makes threads I've replied to disappear?

Thanks.

Makes sense. I guess I'm still a newbie when it comes to how this site operates.

Thanks.
