I have 2 displays (different content) with 2 different resolutions and my
primary display is on right (the secondary have negative X-coordinate and a
positive Y-coordinate).

Primary   : 1280x1024 (at 0,0 like all primary displays)
Secondary : 1024x768  (at -1024,720)

In that case, the status window is displayed outside the visible area of the
desktop after installation.

Workaround : Move the window without the mouse (Alt+Space to show the system
menu, select Move by keyboard, Left-key to start moving and after you can use
the mouse to put the window elsewhere visible)
