Some applications can not be closed by middle click
Some applications can not be closed by middle click (Skype) Fix!
Apparently, it's a new FEATURE in version 4.5 and up.

Skype gets minimized on middle click, and the same happens when you Alt+F4 or right-click->close the window. It's should be fixed in Skype, not the tweaker.
