Skid: what about this one:
I tested a small app I made at Linux and Mac, but I made a window with flag 0, so I'd expect nothing but a simple window with no features. Yet on Mac and iirc also Linux, fullfeatured windows are created. In this particular case I manually recreated things like dragbars, buttons, etc. to really have my own own window, with its own functionality. Works on Windows, didn't work on Mac/Linux. Well, it somewhat worked, but it was ugly ofcourse, my own dragbar was inside the client area of a normal window.
