Already read posts showing as unread??

[gmc-THOR]

In last couple of days I've noticed many occasions of posts I already read (some where I was the last contributor) showing in both the 'New Posts' listing, and the box on the right of recent posts --->>> as 'unread'...

Even if I read it again - and then switch posts - it appears 'unread'...
Is it just me? or did something change in not a good way??

Those in yellow below are my own posts - clearly I've read them already... Those in red I also read... 2 true new ones at the top...

I see that occasionally. Enough that when I leave the forums I usually hit QuickLinks->Mark Forums Read before moving on.

I usually only see that if I don't scroll to the bottom of the thread or go to the last page.

I have mine set to show newest posts at top - so 'first' page IS the 'last' page...
I shutdown/restarted my browser - and seems to be back to normal... Good old Microsoft... lol
