Thanks, I tried that, but it does not work.
So, what I have done is I logged in
no check mark on "Remember me"
a check mark on "Don't use cookies"
The session ID is OK everywhere except on the names of the forums - there it gets lost.
I think this is a software bug. It's new - worked fine a couple of months ago.
