Does anyone know if you can map other commands to the second (upper) button on the pen? Azdrawing is set up for the lower button to easily become pan, but I was hoping I could do more things with a two-button pen though-- perhaps zoom, for instance. I'm sure I can do it through the general Wacom properties in the Control Panel, but I was hoping to have it work just through the program itself. I felt like it somehow got it to do so back in the fall, but I had to redo my computer, and so lost that setup. Any ideas?
