Fences header is off screen and cannot be closed or moved

Something happened recently on my PC that caused one of the Fence windows to expand to such a massive size that it's header is completely off screen.  With the header off screen, I am unable to move the Fence, let alone close or delete it.  There does not seem to be any way to manually delete a fence from within the program's settings or through a right-click menu, which is an odd oversight.  Does anyone know how to remove a fence when you cannot see the title bar anymore?  Thanks!
