You are good at repeating how much you "have to" repeat the reason for me, yet no reason has been given, and certainly not repeated, other than "Windows does this" and some fictional arguments about third party commodities that may end up moving windows into a position where no gadgets can be reached... (something third party commodities can already do btw, regardless of window size) - no name of such commodity has been given, no demonstration of the so called problems have been given. Other windowing systems have no issues with this. It is just another "because I say so".
