Scratch

I know you all have probably heard of this problem before, so if you can't say anything nice, or helpful, please leave now.

Whenever I leave my account idle for a while, and I switch to a different project, user, home, and so on, (as long as I'm still on the Scratch website) It logs me off! But when I stay idle on the page, for something like, watching an animation through and through, making another project while taking small breaks on the Scratch community, whatever I'm doing, if I were to leave a comment, or reply, it just disappears. I'm logged off, but because I'm on the same page, it appears as though I'm logged in. (It still say "Welcome, henley | Logout" at the top) This is terribly annoying for me, because I have a long password, and I usually put a lot of thought and text into my comments, forum posts, replies, etc.

This is getting to a paranoid point, so that before I post anything, I have to copy it. Then if Scratch logs me out again, I can come back to where I was posting, and paste it. Even though I can do that, it's still annoying to have to remember to copy it, log back in, and re-post it.

I know, I know, You're probably thinking, "Why the heck would you go to all the trouble of making this post if the answer is in another thread" or "You should really go research some of the other threads before posting one like this". Well, I did look around. All of the threads I found were either unanswered, or didn't work for me. I am using a Snow Leopard MacMini, and running Safari 5.0.2.

Does anyone know how I can fix this problem? I've been trying to ignore it for the past 5-6 months.

This forum post is actually one of the "disappearing posts" that I had to rewrite.
