[ka-Map-users] Handling large raster data sets

[Paul Spencer]

A bit more on this.  With the CVS version of ka-Map I have about 6  
map files configured and switching between them causes no problem so  
I don't think it can be there.  I suspect it is something in the way  
the map file is set up.

Your best bet is to upgrade to the cvs version and if it still fails  
perhaps we can help you out.

Cheers

Paul
