- Start the program and navigate to a picture file
- Double click on the file
- If in window mode, switch to full screen (using middle button)
- While in full screen mode use middle button to switch back to file browser
- Double click picture file again

At this point with old code I had "fullscreen" window (it has visible
borders - bug introduced somewhere between 0.9.15 and 0.9.16). I can not
move this window to see if it has caption or not.
With your patch I see the the same window but shifted down so it's
caption is visible. And of course I can move it around.
