not really bugs, but certainly a problem: 1. Point lights do not retain their scaled size after saving a scene file, and are difficult to move with the move tool ( they move but very slowly) Using the Trans Dials works a bit better but is a cumbersome process. 2. Mouse movement is confined to the display, rather than continuing as you click and drag... this ties into 1. Some of what I've read in this thread I've experienced too, but other things have not been an issue on my system...... Weird! I hope these two things have not already been mentioned :)
