Have you tried loading an existing GPX file into MapSource, and then doing a File / New and then creating the waypoint and saving?

Slightly simplified procedure, you don't need to load a GDB first. Just the GPX. •Start MapSource (regardless of which map loaded) •File / open any GPX file (I think this is what makes it work) •import track from GPS unit or GDB file and manipulate if necessary •File / save as GPX works ok

Sorry for the confusion, I didn't mean open simultaneously. Open one after the other (one at a time). It's the act of opening a GDB and then a GPX that "prepares" MapSource to run without error. However Red, you've never seen the problem have you?

Agree, frustrating that they would leave this for so long. Vista? Try this workaround: •Start MapSource (regardless of which map loaded) •File / open any GDB file •File / open any GPX file •File / open the GDB file again •File / save as GPX works ok

Yes I know, but it's a pain when you're doing a lot of trimming and editing and saving. I'll do a dozen or more in a session. I would rather not have any GDB files, just the industry-standard ones. My suggestion looks complicated but it's really not, open, open, and then start load/edit/save over and over again without concern of this crash.

I crash consistently when saving as GPX regardless of waypoints (unhandled Win32 exception) Windows Vista Ultimate SP1 Mapsource 6.15.6 TopoCanada v2 I also tried Windows XP compatability mode, no joy The NoMap trick worked once for me, and then once I had done that successfully I could go back to TopoCanada and save. But now I can't reproduce, back to crashing. When I debug with Visual Studio 2008 it says "Unhandled exception, access violation reading location 0x00000000" so there's an uninitialized NULL pointer. I speculate that some action or option before saving GPX is the reason it works for some and not others. I discovered this workaround and it seems repeatable: Start MapSource (regardless of which map loaded) File / open any GDB file File / open any GPX file File / open the GDB file again File / save as GPX works ok Any subsequent save as GPX in the session works ok so whatever uninitialized variable is at fault is touched by simply loading any GPX Good to see you Red90, now I know the rest of the story ;-`) Where did you find the Trans Canada Trail tracks?
