[mapguide-users] Zoom To Selection

[Paul Spencer]

Michael,

the code is there in Fusion to do this but it was never exposed as a  
clickable thing in the query results, probably because we had no  
compelling need for it at the time.

I've added this as an enhancement request to the fusion trac (http://trac.osgeo.org/fusion/ticket/226 
)

Cheers

Paul
