Is it random which ones are selected?  Is it a shift one way or the other?
Area you able to see this in the demo?  Are some never selected?  Do you
know if you have invalid/odd geometries or data in those areas?  If you
have a PostGIS instance handy, you might want to load it up and run
ST_IsValid (http://postgis.net/docs/manual-2.0/ST_IsValid.html) or similar
functions to see if there is any pattern of this problem with something
that might be in the data.

This isn't a lot of detail to try and figure it out.  You might be able to
get more info from checking the requests and responses in firebug (i.e.
perhaps it is a bad request vs. bad response vs. bad handling of a correct
response, etc).

I hope these ideas lead to something useful.
