Hi Windy,
What I wrote was true for me. I do not know exactly how to publicly share the set of botched map versions (since NMConnect is mostly down these days), but I am going to try something. Bear with me. I just added an unnamed page to one of my sites which has three map images:
http://myhealthmaps.org/---.html [This link removed 02-17-13]
First image is the map as published elsewhere on the site as an image and PDF
Second image is following attempt to graft "Yasko" branch from right to left
Third image is after trying to move branch back by using "undo".
Believe me, I have done this so many times and gone nuts that I had to find a way around it. My way is the best I can do.
I just tried to paste three images here and can paste one, so here is the third image on the linked page above. I probably do not need to say that all the branches on the left which have moved below the midline were all nicely arranged on the left in the space now left open after the grafting attempt.

Here is the link to the original map image and PDF. If you want the NM5 map to play with, I can email it to you, I guess, since I do not know how to share the map itself online.
