When starting any application, it often occurs that its window list button is
placed randomly in the list, while a second instance will get a window list
button at the end of the list, as anyone would expect.

Also, the buttons sizes appear to be random. Even so random, that when the title
of a window changes, the buttons all get resized.

I have created a little video demonstration at
