[Qgis-developer] how to about extent re-calculation when resizing qgis window

[David Silva Barrera]

Hi All, 

How can I stop extent modification when I resize qgis windows? I mean, I
focus on a given zoom (map extent) with qgis maximized and for some reason I
need to restore window and reduce size to see any other application back.
But Qgis modifies the view so I lost perspective. I don't care if I can't
see the hole map if I still can see the same area with same zoom.

Any help?

Regards,
David
