We have just uploaded a new version of 3D Topicscape Lite. It is available from the usual place: http://www.topicscape.com/download5.php
and is free to all who have a license. If you are using 3D Topicscape Lite in the 30-day trial period, you can switch to this version now, as well.
This version has a significantly-improved start-up speed and some bugs have been fixed. Enjoy!
