If I import a GPX file that has multiple tracks, and then load more than 1 track into orux, any waypoints that are in the GPX file get imported multiple times (once for each track loaded).
For example, if my GPX file has 5 tracks and 6 waypoints, then when I have imported the file and loaded the 5 tracks, my map 5 tracks and 30 waypoints -- 5 copies of every waypoint.
I'm currently running v 9.6.2 GP, but this problem has been there for a while (multiple versions). It didn't always happen though -- I remember that at one time I could load multiple tracks and would only get one copy of each waypoint.
