The problem Christian is that we can create a situation where it would be impossible to scroll the window. While I could see that you believe that it is a result poorly design application, it comes do to ensuring that it is possible.
I don't think that what Mark has proposed is less elegant. I think that restricting the thumbs to the vertical area of the window was perhaps a premature optimization of the design. I think that we could end up with an overall more usable design if we started to "think outside the box" there :-)
