@rob: In order to user version 3.2 of Google API, install OpenLayers 7.x-2.x-dev and there is a dropdown in Layers, Api Keys Tab If you use Google Maps v3, an API key is not necessary.
This is the best cocktail of modules that really unleash the power of Drupal 7. My sincere congrats!
I have a quick question: For the first view, there is no Openlayers Data Overlay option in Display Format . How can I enable it?
Thanks a lot!
