How to reset the position of KiCad window on MacOSX ? ( windows is placed too high)

I’m using twin displays on MacOSX,

I often encountered a problem showing below

one or more window is positioned too high, that I cannot move it via a top bar.

How can I deal with it ?

OK

I make it I change the menu bar between two displays, and show one of the windows, and move it off the top , then change again , move another …

I think it is because the wxWidgets or Kicad failed to calculate the screen position when have two displays
