[Qgis-user] Dereference plugin not working

[Bertrand Houdusse]

Hi Damien,

If this is related to the classic problem of the Georeferencer's
disapearing window (almost everi time due to the use of dual screen), and
if you are on Windows, I recommend you to test this procedure :
- start Qgis
- click on the georeferencer button
- if the window doesn't appear, and if Qgis' main window looses focus, that
means the focus has gone to the georeferencer's window. So you just have to
immediatly click this combination :  Windows logo key + Left Arrow (or  WIN
+ RIGHT ARROW) ; this is the shortcut to maximize the active window to the
left (or right) side of the screen (link
<https://support.microsoft.com/en-us/help/12445/windows-keyboard-shortcuts>
).
If the georeferencer's windows doesn't show up, you can click the
combination several times until success
This usually works fine for many people on Windows (WIN 7 to 10). I don't
know if there's something similar in Linux or Mac

If this solution doesn't solve your problem, that may be because the
georeferencer's window is reduced in a bottom corner of your screen
(Windows OS again) : you can take a close look at the two corners and
search for this reduced window, that can be very small.

Good luck

Bertrand
