I have installed the Google Earth Plugin for Google Maps and it turns blue when you start to zoom in. It works fine at the global scale and turns blue at about the state level. It shows roads and places, but not land features. This is not water. I am having this trouble with both IE and Firefox and have had it on two computers. One old and one brand new. Both are running XP pro. Google Earth itself works fine. I have tried clearing the cache and switching between the two operating modes - that fixed a problem with Google Earth, but not the plugin problem. I need the plugin for another piece of software.
