I have no idea if 1 or 9 is "high" priority, so I took something in the middle.

Was the GPX created in MOBAC or just loaded? Can you provide the GPX file?

[habanut]

I now recreated the same error with 1.9.9. What I do: I load (the attached) GPX file (Location: Tenerife) and then delete waypoints from the end. Sometimes, the confirmation dialog (do you really want to delete this waypoint) appears TWICE for a deletion. If I OK the duplicate dialog, then the exception occurs, So I think the error is earlier in the duplication of the delete dialog. The GPX file was created with TrekBuddy on a Ericsson Elm phone.

PS: It would be nice to have some graphical feedback in the map display before deleting a WP, but that's more a feature request,
