Connections are selected by cursor coordinates within the shape formed by the connector curve and a boundary closing straight line between the ends, and connector selection takes priority over component selection such that, if a connector curve closed-boundary shape passes over a component, it may be difficult - or even impossible - to select the component.

For all but the most trivial models of a few components in a straight line, this makes selection problematic.

A fix: Allow the user to select e.g. straight line connectors so that the closed-boundary shape is the connector itself and component masking cannot occur.
