Sorry, I do not understand exactly what you mean, but in 1.2 you were able to move points, and it would readjust the lines that join them. A different issue is when it stubbornly wanted to put a point somewhere and you moved the mouse a lot but the dot would automatically go to the place you do not want, and the lines still follow a wrong path. You could also add points too, the interface sucked, yes, and due the tile problem it seems to do whatever it wants sometimes, but the poor tool was a bit more than everyone experimented with 30 secs of play. Of course, in past years the algoritms have evolved, see for example the concept of freehand sketch selection: http://vision.ai.uiuc.edu/~tankh/Selection/selection.html GSR
