I have three diagram views on a form, a single zoomer to control zooming in these views. Sometimes I get strange black areas after placing node via drag'n'drop operation. May be these black areas was the reason of OutOfMemoryException which I've received after zooming. One of the views disappered, instead there was a white window with crossed red lines.

System.OutOfMemoryException: Недостаточн&#1

Yes, I use a dash pen for links. Something like:
[code]
Shape.Pen.DashStyle = DashStyle.Dash;
Shape.Pen.DashPattern = new float[] { 10, 10 };
[/code]

Thank you, I'll try.
