I have a blog where I am trying to get the MTGoogleMaps plugin to work, I have input the API key, the process tags plugin, and the MT code properly, but when viewing the entry, the Google Maps area displays as a gray box w/ the Google buttons/code (zoom in/out, overview, etc) and there is no map at all.
This is the test page: http://www.connecticutsar.org/sites/2009/06/map-test.html
The source code makes me think the plugin is executing correctly, but I can't figure out why the actual map will not show up. Can anyone help?

Just a hunch, but check for JavaScript errors on that page. Google's services are very big on JavaScript, and either something may not be loading correctly (the plugin might be out of date or badly implemented) or it might conflicting with other JavaScript you have on the page.
