Hi Nathan,
I haven't seen the problem you describe, but that's because I use the DrawingAttributes object to reset the rendering parameters of the shapes:
layer.getDrawingAttributes().setLinePaint(newColor);
You might want to check out the OMMouseMode in the beta version of OpenMap, it has very similar behavior to what you are looking for. Combined with the com.bbn.openmap.app.Main application, it gives a different application experience that the former version of the OpenMap application. I've enclosed my version of the properties file I use with that class. I haven't totally integrated the properties into the beta distribution because the Main class component properties are not the same as the default ones on the openmap.properties file. I just run the Main class with a -propertes <path to ommain.properties> flag.
Hope this helps,
Don
