I am using 1.4 beta, and sometimes I see this error:

It spins for a while before crashing like this.
The diagram is small (less that 10 nodes).

I suppose there is a bad recursion somewhere there.

I don't think it is related to arrow heads and such.

Most likely it's due to the fact that I switched to Silverlight 4 few days ago.

Do I need another build of your library?

Thanks,

I use some dashes pen, but I don't set the dash array.
Just this:
link.Pen = new Pen(Brushes.Green, 3.0, DashStyles.DashDotDot);

I will try this SL4 build.
