Here's the problem: I can't make the changeset smaller. It is usually just the split of one single way. > b) When you had an abort, after some time (e.g. 2 minutes) do an update of > the data (file menu).

I found an easy solution that works for me. As the internet connection is very fast and rockstable I can safely assume that the server got all my data. Now I hope that there was no real conflict and simply delete my data layer and redownload. Everything's there. This of course will fail as soon as there is a real conflict. > Until we get a better upload protocol or someone implements a clever "take > my last changesets and test if current changes match" algorithm you need to > live with that issue. I'm aware of that now. regards, Martin _______________________________________________ josm-dev mailing list josm-dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/josm-dev
