Simple Graph Demo - Link/Line length

[Athabasca]

Hello Kambiz,

I have a problem in the Simple Graph Demo:
A Link/Line placed on startpoint X=1 or Y=1 can no longer be reduced by select the endpoint.

Can you help?

I use Version 2.72

I took a look at the bug and found its origin. But it is not easy to fix because needs some major changes on logic behind dragging.
