Bug in Map Cdev
---------------

The Map Cdev as delivered in System 6.0.x has a bug in 
the distance calculation.

To see the bug do the following:

	Find Amsterdam and Set as the default location.
	You will see that the distance form Amsterdam to Amsterdam is
	0 Miles.
	Now click on the word 'mi' and see the word change to 'km'.
	The distance is now 10 kilometers...
	Click on the word 'km' and see it change to 'dg'. The great
	circle distance in degrees is now 360.[I think it ought to be
	0 (zero) degrees, but 360 will do me fine]

	This 'click on mi/km/dg words' is not documented in the Macintosh
	Utilities User's Guide, but I think the bug is worth reporting.

	This bug is not in every location in the Map database, some locations
	will give you zero miles and zero kilometers. A real fun location
	to try out is Denver: it is 10 miles/10 kilometers from Denver...
	The same holds for Salt Lake City.

	Another strange phenomena is in the degrees display:
	Cities on the northern half of the globe are 360 degrees from 
	themselves, cities in the southern hemisphere are 180 degrees
	from themselves.

Anybody care to comment?
