This happens occasionally to me as well. I thought it was just my computer, but it seems not to be just me then. Not so much location, but I'll be reading one character's posts, like I'll go on to, say, my character's posts to see what I've made reference to and what not. All of a sudden the page will freeze, reload, and I'm staring at everyone's posts, not just my characters. I've checked the address bar, and it still says that I'm looking at my character's posts only.
