Hoping someone can help. As a long-term Mapsource user, I've now had to migrate to Basecamp. When viewing a Basecamp track in Google Earth, I seem to completely lose the altitude projection i.e. if I clamp the track to ground, the track can be seen. If I select absolute altitude (with 'extend path to ground), I cannot see either the track or the vertical 'path to ground' lines. All I get is dots at the top of each logged point. I have ruled out this being a Google Earth issue as a previously saved track (from Mapsource) displays perfectly.
Any ideas?
