I think I may understand what is going on - it was hard for me to picture yesterday because I have never experienced it myself. But basically what you are seeing is an IFrame that has been invoked by JavaScript. An IFrame is the only way that you could be experiencing a mini-scroll within a scrolling window. Now here is the unfortunately part ... unfortunately, it is not a result of DaniWeb's design at all. It is actually due to something being wrong with the code from Google in displaying the Google AdSense text ads. If you could describe the problem to me in detail, I will submit it as a bug report to Google.
