I do a lot of cut and paste track editing in Mapsource, i.e, I will locate a section of a track I want, copy it to the clipboard and then insert it into another track using Paste. I just tried to do this for the first time in BaseCamp and ran into a couple of problems. I wanted to append a segment of one track to the end of another one. But the BC track point listing does not have and "end" line like Mapsource. Thus you can only append the segment before the last existing point. Of course when I did this, it drew a line from the end of the new segment back to the end of the original track. I thought I would just delete this point. But after several tries I couldn't get it to look right. Plus every time I deleted a point the display jumped up to the first point. I quickly lost patience and went to Mapsource to do the editing I wanted. I assume that if I had kept at it I could have figured out how to delete the correct point. I think Mapsource has a track join tool, but I have never used it. I don't see a track join tool in BC.
