Hello,

I have a small problem with my gmapfactory application.  The application
uses the query function to select points from a shape file.  The problem is
that the query only works when you drag a box over the points (ie. Doing a
rectangular query).  When you simply click on the point nothing is selected
(ie. The layer does not return any results).  I have already tried changing
the TOLERANCE and TOLERANCEUNITS in the map file, which does not seem to
have any effect.  

Any suggestions would be welcome.

Thanks,
