Over the past few days, if I post in a thread, it then goes back to the threads view for the current forum I am in and the thread I posted in is bolded as if not read. If I go back into the thread and then back out again, it is the same. If I select Quick Links and mark the forum read, it still remains as though unread. The only way I have been able to mark it as read is using the Quick Links and selecting Mark all forums read.

Something seems broken with the thread markings.

Yes I have removed all temp files, cleared the cache and even cleared the cookies as well.

I have also noticed that on several occassions it says I am loged in twice, when I only have one window open.

Also this isn't during the times when updates to the website seem to be being done, when banners don't load and images are missing, this is when the page displays correctly.
