Well, actually, I programmed it so that if your browser is less than 1000px wide, then don't move the ad. So, there is an unfortunate spot after 1000 but before about 1280 where you will get this bad effect.
I can see the problem on my laptop. I will be able to fix this, I just need to contemplate how to do it. It's a balancing act to make it look right in every configuration. Just need to do some math.
