Brent,
So far today everything is working ok for me. A little slower than it was at first and a couple of times it acted as if it changed pages when it entered a post, but they went in ok. My big test will be from10:30 on our time as that was when I was having all of the weird problems. But yesterday I had now with either computer or my laptop and so far today everything is good. If I can get through today without any of those things happening when the load gets heavy, I think you have found the problem or at least the major one.
