This software is compatibile with the Treo 650 only in either of the
"Toggle" modes. It may be compatible with other Palm devices in the
"Enabled" or "Disabled" modes. 

When run, there are four options:
	* Touchscreen enabled:  Allow touchscreen to be used
	* Touchscreen disabled: Lock the touchscreen
	* Toggle with side button
	* Toggle with Opt+Side

If "Toggle with side button" is enabled, whenever the side button is
held for about half a second, the touchpad state will be switched from
enabled to disabled, or vice versa. If "Toggle with Opt+Side" is selected,
the touchpad state will be toggled when the Opt button is held and the
Side button is pushed briefly.

If system sounds are enabled, the Treo will beep when the switch is
performed.
