[Qgis-developer] No Zoom to selected point

[Bernhard Ströbl]

Hi Marco,

of course it is undefined, but IMHO something should happen if you click 
"zoom to selected". If I have a cloud of points and nothing happens I 
have no means to see the particular point I selected and that is worse 
than "unconvenient".
How does other GIS software handle this problem?
