There is no Tip #26.

Tip #25: GPSy supports Contextual Menus. Hold down the control-key while clicking in the map window to easily copy or upload map waypoints.

Tip #24: The latest version of QuickTime is 3.02, you can download it from:
   http://www.apple.com/quicktime/

Tip #23: Updates to GPSy™ are released quite often, so check the website every month or so:
       http://www.gpsy.com

Tip #22: Use the “Copy map point” command and a text editor or database program to quickly build waypoint and route lists.

Tip #21: You can cancel this operation by typing Command-. (period).

Tip #19: Patience is a virtue. A fully loaded PowerMac G3 is pure sin.

Tip #18: Many universities have map rooms (and scanners) in their libraries - a great source for scanned maps.

Tip #17: GPSy supports TFW (TIFF World) calibration files. 
  See:   http://www.gpsy.com/faq/maps.html
for more information.

Tip #16: The bearing indicator doesn’t always point directly to the next waypoint on large scale maps because GPSy uses “Great Circle” routing.

Tip #15: USGS Topo Map (DRG) CD-ROMs aren’t copyrighted so it’s perfectly legal to buy one copy and share it with all your friends. 

Tip #14: Send us your own map tips and see your name in lights:
                tips@gpsy.com

Tip #13: The “Locate” command under GPSyLink™ will center the map on the current position. Be sure to switch the GPSyLink type to “GPSy Digital Map.”

Tip #12: Save calibration files in their own folder with easy to find names, rather than the esoteric original TIFF/JPEG ones.

Tip #11: “Create Previews” for maps before calibrating them; the calibration files will then be “previewable.”

Tip #10: GPSy™ takes advantage of virtual/RamDoubled™ memory when opening large images due to its image cache structure. However, for best performance, turn VM/RD off.

Tip #9: All customer support is handled through e-mail: 
  Report bugs to:  bugs@gpsy.com
  Technical support:  support@gpsy.com

Tip #8: Large JPEG images that won’t open in GPSy™ and other QuickTime® software can often be downconverted to 256-color TIFFs.

Tip #7: You can drag and scroll the map by holding down the space key.

Tip #6: You can scroll maps using the ArrowKeys and zoom in and out with the  Apple-ArrowKeys.

Tip #5: Reduce or slice up large maps using your favorite graphic program to improve speed.

Tip #4: GPSy™ compatible digital maps can be found at :
            http://www.gpsy.com/maps

Tip #3: Reducing monitor colors to 256 colors will improve speed and conserve screen cache memory; although maps display best in deep color spaces.

Tip #2: GPSy™ uses system temporary memory rather than application memory for map image caches. Quit other apps and turn VM/RamDoubler off for best performance. 

Tip #1: I suggest getting some coffee…

Creating low-resolution image cache...
    (Command-. to cancel lo-res cache)

Caching large image file to memory. The map imaging routines may take a few minutes on a slow machine.
