Thanks to everyone. Some good suggestions, however, would feel more assured if ORBX could find a decent solution and perhaps fix the issue?
After installing the latrst product from Orbx, TrueEarth North, I noticed that the transparency option in ORBX Central remains unchecked, despite checking it and closing the control panel. I cannot seem to get any transparent roads to work. This feature does work well in TE South, but not in North. Any help will be apreciated.
