Re: [OpenMap Users] OMLine.distance()

Hi Ed,

What version of OpenMap are you running? In the latest version
(4.5.4), the distance for OMLine is actually directed to the
OMGraphic.distance() method, which makes a decision if
BasicGeometry.distance() or BasicGeometry.distanceToEdge() should be
called. For OMLines, distanceToEdge is always called. I haven't seen
the problem you describe in my version.
