Not resetting posts that have already been seen

[RightHere]

When I close the browser and visit the site again, the icon in front of each message used to change color (and maybe the icon changed too). This made it easy to see which posts had activity since the last logon. I don't get this anymore. Anyone else having this problem?

I'm using Windows XP + all of the latest IE patches.

Nope, works fine on both my XP & 98se machines. Have you tried clearing your cache and ALL cookies? Just sounds like a messed up cookie

Yes, I've tried that multiple times. IIRC, that only fixes it for a very short period of time.
