<t>I've downloaded the source and trying to understand by debugging the code. <br/>
It appears the behavior I'm describing is contained within the "paintOtherLevels" method of the PlanComponent.<br/>
Unfortunately I'm not a native Java speaker, so it's taking me more than a few moments to grok it ...
