So the word from the ADV Elves is that the attachment feature for GPX files should now be working correctly again. This does not mean that all older attachments will work. As a matter of fact, I just tried to download some older tracks and they do not download. But, it does mean that new files should attach correctly. Please note - you cannot attach GDB files, only GPX files with GPS info. To download a file, right click and choose Save As, save it to your computer, and then open it in Mapsource. If anyone has problems with new attachments, please post a note in this thread with the specifics of what you tried to load or download so we can track it down.
