The CityTrafficSimulator update to version 0.6-6 is online.

The most important change ist the new scrolling algorithm: In order to remove the former canvas size limit it was necessary to get rid of the scroll bars and implement new scrolling metaphors. Changing the currently visible part of the network is now done by drag and drop with the right mouse button. At first, this might occur less intuitive to you, but once you've get used to it, navigating through your network becomes much easier and faster.
