Newbie question here. I have a Garmin eTrex GPS and use the Map Source software that came with it to manage marks, waypoints etc. Having only used it once to down load several loc files I was a bit dissapointed it couldn't store multiple locations before sending them to the GPS. I had to load each location (from the loc) file one at a time.

Does anyone out there in Geocacheland have any experience with other software apps, that run on win XP, for managing loc or gpx originated markers on a Garmin GPS?
