Interesting program. I've got a few questions, and a suggestion or two.
First, the suggestion. An undo feature would be slick, for when you accidently connect the wrong node.
Second. I'm not at all clear how to connect disjointed lines. it seems that the edge always wants to go from the previous one, but thats not always possible, so I need to be able to pick up the pointer and just connect this node to that node. How do you do that?
Ach...a little more experimenting, and I figured part of it out.
While 'making' edges, simply click off on a blank part of the screen. Then click another node, and then another, to draw a line between them.
so, I'm happy you could solve your problem. I'll maybe change the behavious of the 'Add Edge' tool, if it is not intuitive.
Anyway, there is also a function 'delete', in the Editing menu. By using this tool, you simply clic on the edge or the node you want to remove.
