>  Below is the simple reproducer.
>  I only succeed in the first time when I try to move the window with the PopupMenu showing.
After that I can not move the window if the popup menu is shown. After some tracing I see
that the window can be moved because the WM_CAPTURECHANGED event is generated and handled.
But generally there are only MOUSE_PRESSED events instead of the WM_CAPTURECHANGED event.
