	I found very distressing effect of working Diagram.GetLinkAt. It doesn't find the necassary link. But instead it finds the another link. I send you the screenshot of the diagram. Look at the right decision node. When the mouse is over the top link the GetLinkAt returns the bottom link. How can I avoid this effect?

	Try setting LinkHitDistance to some small value, e.g. two points. GetLinkAt returns the first link it finds within that distance.

	There is no effect. It was: Code var link = Diagram.GetLinkAt(point, 3, true, ref segment); I try to set: Code var link = Diagram.GetLinkAt(point, 1, true, ref segment);

	I note that it takes place in case when the ended contol points of the links have overlapped coordinates. In my example the start point of the first link has coordinates {262,5;247,5}and the last point {612,5;382,5}. The last control point of the second link has coordinates {612,5;322,5} I see that the X-coordinates is equal and the Y-coordinate is between 247,5 and 382,5. In case like this tha same behavior takes place

	Does it select the wrong link if you click to select it? could you save the diagram to xml and email it so support@mindfusion.eu? Thanks, Stoyan

	It doesn't select wrong link because I overridden the behavior. But it tries to do it . I have to add my project to xml diagram because otherwise you can't deserialize it. I sent you an archive. File with diagram named as diagram.xml

	This should work better: https://mindfusion.eu/_beta/wpfdiag_linkat.zip You'll have to do a few modifications to your project to use the new assembly: - replace ArrowHead with ArrowHeads in the InitLinks() method. - the DrawHandles override (NodeRoutine.cs) now takes a HandlesVisualStyle argument instead of Color - set the reference' "Use Specific Version" property to false I hope that helps, Stoyan

	I found an interesting effect. It looks like a bug. The effect takes place after link.Route() call. I sent you the e-mail with video which demonstrate this effect. May be it is necessary to call something after route for this case?

	Yes, it seems we missed this case (last two points coinciding) when we changed the arrowheads type to Shape. We'll upload a fix in a few days. Stoyan
