Zoom problem

[Carl Burn]

Hello All,

took a break and looked at this again. Revised the extents after opening 
the file produced by gdaltindex in MapInfo and getting a totally 
different set of extents. This centres the map just fine. However still 
no zoom in or out, I tried altering the map scale value in the box below 
the map in the preview window in mapedit and this forces the map to zoom 
in but the mapscript controls for zooming in and out dont work at all. 
Still puzzled but I think I am missing something obvious.

Any ideas ?

Cheers

Burnsy
