QueryMaps & mapext=shapes & point???

The mapext=shapes was intended for a) groups of features or b) single line or
polygon features. Doesn't surprise me that a single point would yield strange
results since the map extent essentially becomes a point. Instead you can use
mapxy=shapes and then buffer= or scale= to set the map dimesions. The mapxy=shapes
calcs a simple centroid based on the set of selected features.

I have tryed querymap function and it's great, but when I want to zoom to a
point feature, the ponit appears in the upper left corner of my image. Is
it normal? Why? Is it necessary to use lat and long to zooming to a point ?
The problem is that I would like to hilight the object that I'm querying to
differentiate it from the others.
Thanks a lot,
