Hi i am running WP 3.3.1 and Map builder 1.0.5 - I have freshly installed WP and the Map Builder plugin 3 times and it looks like it is boken. I have tried it on Chrome, Firefox and Safari.
On initial install of plugin there was no buttons in the editor for accessing map builder features. I found the settings for the plugin and turned on show in side bar, which it did, but when pressing the create new map button nothing happens.
In the editor for posts and pages the editing button have gone after plugin was installed.
Aslo it seems to block all pop ups and makes WP non functional.
It would be great to get this plugin working as it looks like it has a really nice set of features
