When I click on the route, I use to get directions for the whole route at that time I would be able to invert the route. once I made a route in Basecamp Beta and clicked on it I would only get the directions for that part of the route. So in affect, I could not invert the whole rout. also I find it confusing to add way points. Hope this helps.
There aren't, it's the latest beta version ... however 4.2 should be out shortly. However I still get directions and can invert the whole route so maybe something is wrong with your installation :confused:
