First of all, your plugin is wonderful! I had a really easy time setting it up and everything, besides this one TINY bug, is functioning perfectly.
However, I do have one problem. This only happens when I make a NEW search for a location, meaning that the map starts at the initial zoom level on a freshly refreshed page. When I search a location, and have stores pop up on the map and click one of those stores, the shadow behind the store information does not render correctly. If I zoom in, or change the position of the map that fixes the shadow, but initially it doesn't work. I'm using Firefox 18.0.2 so I don't think browser compatibility is my problem.

Thanks a bunch and keep up the work. $50 is a steal for the functionality this adds to my website
