How to fix annoying auto reshape link in a group?

Hi, i’m a newbie and i have one question as the subject

Here the case: i have nodes and links in a group like this

and whenever i move the node “delay” the link between “aggregator” and “delay” is automatically reshaped a lot until mouse up . The problem is the reshaped link is not simple as it was as in the picture below

So is there anyway i can fix this?

Thanks a lot :)

and FYI in the figure above i have enable the propertie for a link to be relinkable and i have that problem. So far, i want the link to be relinkable and reshapeable without that.

i really appreciate the answers :)

Sorry about that. Try the go.js or go-debug.js that is in http://gojs.net/beta .

thanks anyway :)
