More than one kind of touchscreen. Some require 'some skin' to make the
electrical reaction. If the application will be used by people with gloves
on or long fingernails they won't work. Some others just need pressure
applied. Other than that, pretend you do not have a keyboard, everything is
done with a mouse (if you don't have a touchscreen). Lots of cool things in
Foxpro are useless in a touchscreen app because they can not be sized large
enough for fingers to activate. Also put some space between things.
Touchscreens go out of calibration and how often you have to recalibrate is
dependent on how small and close together the buttons are.
You will live in the click event on everything.

Install the drivers. They simply emulate a mouse. A couple things to keep in
mind:
o There is no "Mouse Over"
o Dragging sometimes doesn't work well
o Clicking with your right finger doesn't give you a right-click ;-)
