HourWorldΓäó is NOT to be used as a primary navigational tool. Use of HourWorldΓäó as a primary navigational tool is OUTSIDE the scope of the license agreement. As a reminder, the following excerpt from the license agreement is repeated here:
The following uses are OUTSIDE the scope of your license, and are NOT PERMITTED. If you acquired your copy of HourWorldΓäó for one of the following purposes, and do not wish to license it if restricted from these uses, please return the software or registration key for a refund.
1) You may NOT use HourWorldΓäó as the only source or primary source
of information when making decisions that may affect health, safety,
or economic well-being.
2) You may NOT use HourWorldΓäó as the sole or primary source of
navigational information in any situation.
3) You may NOT use HourWorldΓäó while driving a motor vehicle, riding
a bicycle, piloting an aircraft, or operating a water-going vessel.
Such operation is unsafe. HourWorld's display and text sizes are too
small and too dim to convey information in these situations without
dangerous distraction from your primary duties of operating the vehicle.
Unless you have a GPS receiver hooked to your computer, and are running GPSyΓäó software, the GPS functions will be unavailable. In order to use GPS information with HourWorldΓäó,
1) A GPS receiver must be attached to your Mac's serial port.
2) Run GPSyΓäó (available from Global Mapping Systems -- www.gpsy.com) until
a valid locational fix is acquired. HourWorldΓäó relies on GPSyΓäó to operate
the GPS receiver, and receives its GPS information indirectly through GPSyΓäó,
not directly from the GPS receiver.
3) Select "GPS Location, Worldwide" as HourWorld's current home location.
The GPS Display
 
The GPS display shows an arrow with its tail at the current location. The direction
of the arrow shows the current direction of movement. The length of the arrow
increases with increasing speed. In order to keep the arrow from becoming too
long to display, the length of the arrow is proportional to the square root of the
speed.
The panel at the lower right corner of the map extends to show the current speed
and direction, updated every 5 seconds.
 
Each location appears with the following information:
Location name and current time there.
Distance and initial direction from the home location.
Current effective speed to or from.
Estimated time enroute.
Estimated time and date of arrival, assuming current
speed and direction continue.
To select a different location to appear in the display, click once on the location's
display. A scrolling list will appear to select from. The locations displayed are
the same as in the analog clocks, digital clocks, and phone call coordinator
