Hi,

I removed all the Controller Tools from my NDiagramView because I wanted a read-only diagram.  This works well; however, now I am trying to display tooltips and wonder if they are not working because I have some required Tools missing.  I tried to go back and add the default ones using the designer, but I am getting an error in Visual Studio 2010, something about not being able to instantiate NTool because it is abstract.

Before I spend too much time on this, here is the code I use:

shape.Style.InteractivityStyle = new NInteractivityStyle(string.Format("Remarks: '{0}'", attrib.Value));

I thought that if I hover over this shape in the diagram it would show the tooltip.  I confirmed in the debugger that my InteractionManager is set to a valid object.  Not sure what else could be wrong other than a missing Tool in the Controller.Tools collection.  Any ideas?
