I would like to look into this further with you but I will need a copy of your files to do so. You can post a zip archive of the pages that I will need. I would like a copy of the page with the map on it as well as the google_javascript folder and a copy of the db or the specific table you are getting the info from. I will check on these on my end to see if I can spot the problem.
Normally if you have a map that does not render correctly it is due to bad locations or some conflicting code on the page. When I visited the page just now it looked to be rendering ok so if you have got it worked out already just let us know.
