I'm not sure if saving it clears the active track, but if the active
track is still intact you can read it using GPSBabel (something like
"gpsbabel -t -f garmin -i usb: -o gpx -F outfile.gpx"). If your Vista
is one of the Cx or HCx models, you can set it up to save your
tracklog data directly to the MicroSD card in GPX format. By the way,
I believe "saving" the active track applies a simplification algorithm
to reduce the number of points, too (in whose world should "saving"
something cause a loss of data?!).
