Uninstalling
MapTool does not have a specific uninstall program, but leaves a relatively small footprint on your computer. Here is what you need to do to remove it completely
WebStart
If you used the Java WebStart feature, simply open the Java Control Panel and empty the cache.
Executed from Zip
If you executed MapTool, check your home directory (soon-to-include a description of what that means) and delete the .maptool folder. That will remove all of the preloaded images and any cached campaign information.
