Well, I tried to post a response to this thread in the last 30 minutes or so and got a server busy message after I finished typing my message and hit post. I canceled the reply and went back to searching the forum and had no problems. I have typed responses in a couple of other threads with no problems. Immediately after I got the server busy message when posting, I was still able to go back to searching new posts with no trouble. This is unlike the server busy messages I typically get when moving from page to page in the forum that last for long period of time without me being able to get back in.
Also, I have had the same problems as Thaifood with those square ads. These are the square ads that appear on the right hand side of the first post on a page. Most of the time they are just a picture and cause no problems, but sometimes they are a video instead and I experience the same problems with scrolling when the video plays.
