What browser are you using? I am using FireFox and the Google Maps don't work in it. There is a JavaScript Error. If I switch to IE, they work fine most of the time.
Google maps work fine in Firefox. You've got some other issue causing the problem.
You are correct. My AdBlock was blocking one of the JavaScripts. I hadn't had a chance to look at that yet. Added a whitelist entry and everything is good to go.
