We’re wondering if you actually have multiple nodes stacked on top of each other in the editor. Please try dragging the node and seeing if there’s another one underneath it. This is currently easy to do and we’re working on a new setup to help prevent this. Thanks.
@architek1: As of Vuo 0.6.0, the editor tries to avoid creating multiple nodes in exactly the same spot — it now offsets them slightly, to make it apparent that there are multiple nodes there.
