I keep getting logged out.

I log in then switch pages and I'm logged out. I log in, attempt to reply to a post and I'm logged out. I log in again and my reply has disappeared. This has happened to me multiple times.

I have read the FAQ but didn't see a solution there. HELP!

(This is my second attempt to post this.)
(Third attempt. I just copy the post and paste it in again each time)
(Fourth time)

Each time I attempt to post this I am redirected to the login page although I am showing me being logged in in the upper right.

 

Have you remembered to check the little box "Remember Me."
If you have and it still doesn't work you might want to dump
your browser "Cache." Also your temporary internet files,
and log back in.

 

As a rule I don't do "remember me" on a shared computer so I may have to limit myself to surfin' HDF on the home box. I appreciate your help.
