Can you post your Node template? and also, please use a company email address so we can look up your support status.
The following is the node template
That’s interesting. We’ll investigate.
For now, you can avoid the problem by surrounding the Grid with a transparent Border:
As a separate issue, you probably don’t want the whole node to have go:Node.LinkableFrom=“True” and go:Node.LinkableTo=“True”, since that makes it too easy for the user to draw links and too hard for the user to drag nodes. Instead it is normal to just apply those attached properties to a particular element within the node, such as the background shape. That would let the user drag the node by dragging any of the text or shapes within the node.
I forgot to mention that this bug was fixed in 1.2.6. It only happens in Silverlight, not in WPF.
