Late answer, I know, but... You should know that you can lock the zoom function of the maps in Carbonite. As for their maps moving weird, all can say is that ... It's possible, but I used Carbonite for about five years and never had that problem. Just make sure that you have it set to "follow you" and that you have the maps zoom factor locked. All of that SHOULD be available through the right-click menu on the maps.
