Comment 7 for bug 1244397

that hack didn't work for me, but I figured out another way to move windows into the visible area.

background: i have a MacBook Pro, with my external monitor to the left of my laptop; i open inkscape on my laptop monitor by typing the app's name into spotlight on the laptop's monitor. once i select file > document properties they open on the left "hidden" part of X11's "window". so i can't see or select and therefore can't move the document properties window.

solution:
* open Inkscape
* select >File >Document Properties
* ⇒ New Window opens in invisible area
* create a new desktop in Mission Control
* move Inkscape to that desktop
* close the newly created desktop
* ⇒ app windows from that desktop are moved to another desktop
* ⇒ invisible windows get repositioned and are shown

if it doesn’t work with creating a desktop on one monitor, try it with creating a desktop on another monitor. it depends on where invisible windows are located:

* invisible windows to the left of the visual area become visible doing this trick on the left monitor
* invisible windows to the right of the visual area become visible doing this trick on the right monitor
