Is there any way to make it not do this? Usually when this happens, I still want to read the thread, but it's too much trouble to sort through all the posts to figure out which ones I haven't read. And with so many messages, it takes a long time to load even on a fast connection - I hate to think what it must be like with a slow connection.
