When the page loads, the first thing to load is the underlying HTML page. That page has links to include other files such as graphics and ads. These included objects load later. All of the "boxes" where the images and ads load should have predefined sizes in the HTML so there should be, for instance, a 729x90 box where the top banner ad goes even before the ad loads. What I see once in a while is that a very large square box appears where the 728x90 top banner should go. That large box then quickly resizes to 729x90 and then the ad loads. What is strange is that this doesn't happen every time. I have no idea what could be causing the large box to briefly appear, but maybe there is some old HTML or CSS someplace that gets loaded and then overridden by newer code. I'll try to look around for such a thing.
But, if this theory is correct, what is happening to you is that the large box pushes everything down for you, then the box resizes and everything moves up. Does that sound like what you are seeing?
YES. That's most likely it. I'm on my lap top right now so I don't notice it. I'll post again if I see the jumping happen. Thanks for looking into this.
