First off GREAT plugin!
I am having a small issue on a full size map 900px x 550px. When viewing on the ipad and iphone the page doesn't shrink down to the browser size as it does on all the other pages. It appears to stay the width of the content area and breaks the theme. If I can figure out what is causing that I will post back. I checked on the demo washingtonchurches.net and got the same results as well. To see what is going on just navigate between the map and directory page on the demo.
Also I read in a previous post that the plugin doesn't support geo location....I would be interested in that!
Thanks for this awesome them. Please let me know if you come across anything and if I can figure it out I will be sure to post back.
