Version 3.34 is out in the usual place. Changes:
3.34 - [4/28/08] (Beta)
Added "Garmin Astro" tracking to live tracking. Continuously
downloads tracks from the GPS.
Uploaded saved tracks now preserve track name (if present)
Downloaded saved tracks names now preserved
Track name now shown in profile window, if existing
Added "Add file to Logbook" to right click file menu
Fixed average cadence computations to not include coasting
Fixed missing baud rate with Magellan units in GPS Transfer dialog
Removed NMEA tracking debug info
Astro live tracking was added by request. Find it in GPS->Live Tracking. For "GPS Type" choose "Garmin Astro." Then hit "Start Tracking."
Basically this function continuously downloads tracks and shows the most recent result in the map window. In other words, this will work on any Garmin USB unit, but it's designed with the Astro in mind since each dog track shows up as a saved tracks.
The "center map on position" toggle will zoom the map to fit the *first* track downloaded, after an download is complete. It may or may not be useful--let me know.
The map will automatically redraw when a download is complete, but the display will be a little funky if you pan/zoom the map during a download. You'll get it "in progress" rather than the most updated positions.
We're still working on better support for multi-track files, especially with names. Also, disambiguating clicks when there are (say) multiple tracks in the same area.
