Hello,
there is a little problem with the pane close button template in the Windows 7 theme: you need to move the mouse cursor to the black part on the x in the button for the button to be active. When the button is active, it remains active if the mouse cursor is moved outside the x. It seems that the backgroud of the "not active" state should be set to Transparent and not to null.
Note that the same problem appears with the Office Blue theme, but not on the Office 2013 theme. I have not checked the other themes.
