I built the map application for the page linked here:

http://www.meanderingmaine.com/mapit.php?region=1&county=&category=

The application basically uses PHP to pull location records from a
database (based on search criteria) and then parse that data into a
JavaScript file that creates the map and plots a point on it for each
location record.  My client noticed that three records in particular
are not showing up when the search criteria are broad enough for all
of the points in the db to be called.  This is the case with the link
above.  If you specify Waldo County in the county drop-down, the
points appear.  I checked the php created JavaScript file and found
that the points in question had in fact come out of the db and are
being parsed into the appropriate Google Maps Code in precisely the
same way that they are when I specify Waldo County.  The only
difference is that they don't always show up on the map itself when
Waldo County isn't specified.

My theory is that the map just can't handle this many points and for
whatever reason these ones are being dropped.  I tried manipulating
the code that queries the db to return a different subset of records
that includes these three points and has about as many records as the
subset returned when I specify Waldo County.  The points all showed
up.

It doesn't seem to matter which browser I use or how fast a
connection / how much RAM etc.  Is there a fundamental limit to how
many points can be plotted on a map at once?  Alternately, if plot the
points by Lat/Lon instead of using the geocoder for each point each
time the page loads, might that help?

For reference the points that go missing are named:

"Belfast Bay Inn & Luxury Suites" plotted at "70 Main St, Belfast
Maine 04915"
"Belfast Bay Inn & Luxury Suites for Wedding Parties" plotted at "74
Main St, Belfast Maine 04915"
and
"Molly Amber Gifts" plotted at "72 Main St, Belfast Maine 04915"

to find them on the map, specify Waldo County, and zoom in on the
cluster of points near "Belfast Bay".  They are sort of hidden behind
"Yo Mamma's House".

Thank You in advance for any help.

Peace
