Subject: fvwm misplaces windows

Package: fvwm
Version: 1.24r-25

There is a problem with the interaction between fvwm's menus and
window placement routines that can lead to windows being moved
off-screen unintentionally. If that window is a sticky window which
has 'WindowListSkip' set, it is not possible to bring the window back
onto the screen.

To reproduce the bug:

1) Create a menu for the window decorations that is quite long and has
'move' near the top.

2) Create a window that is shorter (along the y-axis) than the menu
and place the window at the bottom of the screen.

3) Click on the window border to activate the menu. The menu will be
displayed with the bottom of the menu at the bottom of the screen and
the pointer will be warped to the top of the menu.

4) Click on 'move' on the menu. You may now move the window using the
mouse, and the pointer will be above the top of the window. (You may
place your window off screen because of the offset.)

5) If you do not move the pointer after clicking on 'move', the
pointer will be warped to the border of the window, however, the
offset described in (4) is still in effect. If you click without
moving the mouse, the window suddenly moves so that the distance
between the window and the pointer is correct. This may mean that the
window is misplaced off-screen.
