Yep, it used to work so great in older versions. And then, well I don't know, someone decided that default system windows are not cool enough and WinBox will be soooo much better drawing own custom windows. So window menu and possibility to close it using upper left corner is gone. And the fixed visual style as an "added bonus", well... the bluish-purplish color looks bad unless you set the same color for all windows in the system and the buttons look wrong with any visual theme available in Windows. Why did they have to touch it at all?
