	The Tracking Box is a window to the upper right of the primary
image area.  When a primary image is displayed, the Tracking Box contains
a magnified portion of the image.  The portion of the image which is
magnified depends on the location of the pointer when it is in the
primary image.  The primary image display is typically 512x512.
The Tracking Box shows a 100x100 portion of the image which is magified
2X to give a 200x200 display.  The Tracking Box image is updated as
the pointer is moved around in the primary image.

	If the pointer moves out of the primary image, then the last
portion of the image displayed remains in the Tracking Box.

	The Tracking Box may be toggled ON/OFF with the Options
submenu Tracking button.  The Tracking Box may be moved by using
the Move button of the Extra submenu; click MB1 in that button,
then move the pointer to the Tracking Box, depress MB1 and keep depressed
while moving the pointer to target position.
