New to Java and having fun learning it. Please be forgiving of my ignorance. I love stackoverflow, because everybody here knows so much, and my books don`t cover everything I want to know. I am familiar with C/C++ concepts (Win32/64 API), raster operations, graphics formats, the ESRI shapefile format, GUI implementation and event dispatching, and tile caching. If you were wondering about my user name, it`s a spoof on William the Conqueror ©
