The reason you are seeing such a huge size difference in the editor is that the TSU9600's screen packs 640x480 pixels into the same physical size screen (but turned 90 degrees) as the Pronto NG line of remotes which have a resolution of 240x320. So for purposes of programming with the editor the page size you are working with is 640x480 when at 100% zoom. To see how your CCF will look on the actual remote simply launch the Simulator. The Simulator is the exact same size as the physical remote. What you'll find is that your imported CCF is hardly taking up more than the upper left quadrant of the screen. As such, the stylist will need to be used once downloaded to the remote for comfortable operation until you have created a new layout via the editor.
