This is not hugely important, but it is annoying nontheless. For some reason, threads that are marked as unread when I arrive at the forums are being marked as read once I read one thread and return to the the listing. Not just the thread that I just finished reading, but all of them, are being marked this way.

This is a little annoying as I like to read through all of the developer threads, or at least most of them, and this is making it hard to do so. This has only been happening the last couple of weeks.
