Top of Panel Stuck off-screen

I somehow managed to drag one of my panels partially off the top of the screen.  Now I can't get to the navigation bar to drag it back where I want it.  Using Shift-Windows- key-left will move it to the 2nd monitor.  But nothing else has any effect.  I tried exiting Painter 2015 and reloading but that didn't change anything.  The Window menu just opens and closes the panel.  Does anybody have any idea how to move the panel (or reset its position) with something beside the mouse?
