Problem with View Posts since last visit

Anyone else having this problem? It doesn't work properly for me, always says "no new posts since your last visit".

I think it's a problem with cookies, because I keep getting logged out then in again, but in that interval of a few seconds, there are obviously no new posts so nothing shows up when I use this feature.

It used to work fine for me a while back (sometime last year), and Ballack also reset the board cookies and it worked ok for a few weeks after that, but for the past few months it's not been working again. This happens to me on multiple computers, even when I'm travelling to a different country.

Did some googling and found this:

Does that help...can something on the board be fixed or is it a problem with my computer/internet connection?

Never had a problem Kas so it is likely to be all your fault

Which browser are you using ?

Do all your passwords / cookies etc get wiped or is it just this board ?

Happens with all browsers: Firefox, IE, Chrome.

And it's just this board (although I don't use too many other forums and definitely don't use any other forum which has a "View posts since last visit" feature).

It saves my login status if I close the browser and open it again, but I think that's only because I have the "keep me logged in" option checked, and it basically just logs me in repeatedly every time my connection/cookies log me out.
