After viewing so much of the art here, I can see where a graphics tablet allows for much more detail than I could possibly create using a mouse. However, I do have another question. Is there an on/off switch for the tablet? If the tablet is always on, how does that affect the use of the regular mouse in other programs such as Word, PSP, etc.? I use a variety of software and don't want to be locked in to using the Graphics Pad controls once I've installed it.
