It keeps working fine, now, I even stay logged in now when opening the forum from the gallery. Before, I had to log in again whenever I opened a new window, and it would not always work.
I did not change any settings on my computer, and I tried it on 2 laptops and an ordinary pc, and they all work OK, now.
I have a new OS on my laptop, Vista drove me bonkers, so we installed windows 7. I am not used to internetting from my laptop, because of my problems with vista, so maybe I have been messing things up, myself... I know that my laptop does not save passwords, but that is intentional. I don't want other people to be able to log in under my account. But as long as I do not log out, I am supposed to stay logged in...
Anyway, it works fine, now.
