I am having an issue in Firefox - NOT the new one - where the threads that I've read don't show up UN-bolded after I read them. All the threads in my list remain bold as if there were new posts in them. I just double checked and I'm not having the same issue in IE. Is anyone else finding this and, if so, is there a remedy? Btw, it's begun happening only in the past couple of weeks; before that, it was working the way it's supposed to.
