Hi Ross

Thanks for the info. I will give it a shot and look for the node count.  

I have when creating a way found hovering back over it down the bottom of the screen it will tell me the nodes used. 

What I have found if I create a way of say 1500 nodes and upload, then create another way of say the same number of nodes, and then upload and finally then create a multipolygon relationship and tag the properties and upload all works well. But if I do it in one step and then upload I strike the mentioned problem.   My worry is multiple uploads as they are a pain to find, edit and or remove.  Just want to keep OSM data a clean as possible and not corrupt the database. 

From memory moving a large multipolygon lake in JOSM creates a similar problem. So I align lakes in Polatch 2 and all works well. 

Finding JOSM very powerful but still very much a newbie with it.

It is then a simple matter to split (Tools->Split Way) the way into two (or more) pieces.  If its a loop way then select two (or more) nodes on opposite sides and then split it.
