Thanks for the response Richard.  I have the queryfile working and it is
saving the the selected feature but the problem I'm having is that it's
returning the layer's query template when I pan or zoom after the initial
query.  What do I need to do to interact with the map after the query and
still have the selection higlighted on the map image(using the the
queryfile) but not trigger the query template to show up.  The
documentation suggests that using a Browse mode will just produce the map
image but thats not happening in my app.   Am I missing something?  I see
that it works well in your example.

Thanks,
DaviD


Well I guess you are missing something, but I'm having difficulty
envisioning just what it is.
When you do the query you set:  
   mode=itemnquery
   qlayer=x
   savequery=true
   etc....
Now you have a map and a saved query file. To pan or zoom, you want:
   mode=browse
   queryfile=name_of_query_file
   etc....

Do you have a template difined for the layer  that displays attribute
data? In many apps you want to be able to hilite the object (itemquery
or itemnquery) and you want to be able to click on the object and
display attribute data (query or nquery). I do that by basically
defining the layer twice with different names and different templates.
