• Added Teale Albers support for Teale California CD-ROMs (thanks Jerome Yesavage)
-- use "100 (Teale Albers)" for the UTM Zone and "NAD27CONUS" for the datum
• Added support for Japan Map Center Digital Map "SHADE" file calibrations on the 1:200000 scale maps
• Added check to make sure GPSy doesn't place windows offscreen when a PowerBook is "undocked"

Release 3.20r2 -- October 30, 1998
• Added support for MapFan PUE Routes (r2)
-- route files begin with the header "144"

-- to change the routename / route waypoint names, change the header to:
144,XXXX,YY
-- where XXXX is a four character routename, and YY are two characters to use for route waypoints
-- to upload as a background track, change the header to "16" (from 144)

-- now the KANRI.CSV file can be in the same directory as the map files, even on 1:25000 scale maps
• Added limiting of 24 bit images to < 4000 pixel width due to QuickDraw (MacOS) bug (thanks Allory Deiss)
• Fixed "About" panels so that they display the correct version number
• Fixed splash panel delay action
• Fixed rare problem trying to upload data via drag-n-drop when serial port was set to "none"
