You are probably right. Try using the Thread Tools in the upper right to mark the forum read before you leave.

thanks

Thanks for the tip Neal. I would like to know that you are still looking into the problem though. Might this be the case?

Also, part of this issue is that at some point (after a period of time or each morning/evening?) most threads are marked read, except for the ones I've actually read. Basically the behavior one would expect a guest to see I believe.

I noticed this problem start a while ago and posted a thread, and Rockin' Robbins also noticed that the forums were not remembering which threads he had read. He was using different OSs and different browsers.

I too am using multiple machines and diferent browsers. For example, on my machine at work, I can read a bunch of threads and then go home, whereupon my home PC upon logging in, displays the threads as unread. This never used to happen, so I would imagine that some part of the forum software that tracks what threas usernames have read has been broken or disabled - that's the only way it could have ever worked and is therefore not browser or OS related. I have tested this on different machines, different OSs and different browsers and the results are the same, subsim doesn't remember what threads I have read, but my individual browser does. This causes a problem when I move machines / locations.

Yeah, obviously something somewhere in the vBulletin stuff needs to be checked. I am reading through the support forums, will be trying things. thanks

A bit of additional info - This started at exactly the same the default colour scheme changed from black to white. I'm assuming that this was the result of a forum software update, which would make sense, as they wreak havoc on previously undisturbed settings like 'track posts'.

Just a heads up, but this is happening again. My own posts are sometimes marked unread and it appears to be anyone's guess just when it decides I've read someone else's.

I'm curious who else has this issue so I've opened a poll to find out if I'm in the extreme minority.

Yeh, I have the same issue aswell.

Haven't encountered any problems.
Vista - Firefox.

It happens to me - XP/FireFox - but to be honest I've never found it anything more than a very minor embuggerance.

SUBSIM's read/unread functionality has been screwed ever since I first arrived... er, two years ago? It doesn't really bother me.
