[ka-Map-users] Panning and zooming question

[Paul Spencer]

dejan,

that would be great!  First thing to try would be removing groups and 
seeing if it works that way, then start adding groups back in I guess.

The difference in the new version is that each group is put into a 
separate layer and requested as separate images.  They are also cached 
in separate directories on the server side.
