I've had this happen 2x now. It might be the new computer I'm using, but is anyone else having a problem with the markers for new posts in a thread disappearing? I'm getting half way through reading all the new posts since my last visit and then the rest of the markers go away so I have to figure out the last post I read. grrr.

BTW, saw a little bit of the movie Australia. Have they no production standards?

I've never had that problem unless I navigate away or my browser shuts down.

Nor me, though if I read them all, go do something else then come back, the markers are usually back again even though there may be no new posts.
