conflict manager: do not block josm totally

[skyper]

Hi again.

It would be superb to be able to move around on the map with an opened conflict-manager-window to investigate the conflict. Especially with big areas you often only need to look at some nodes but I have to close the conflict-manager-window to move the map to be able to investigate these nodes.

Thanks

I think this would be an important enhancement. If one has to resolve more than, say, five conflicts opening and closing the conflict manager over and over again gets on ones nervers.

I stop editing today, cause there was someone else editing in this area and I got conflicts over conflicts. These were all conflicts on moving some ways with their nodes but it took me more time to solve the conflicts than I had spend editing.
