In the past, using PP, P5, P6, I would never touch D|S. I tried, but no prevail. I purchased Bryce 6.1 and D|S has to be installed (about 2 months now), which comes with Bryce 6.1. I wasn't pleased when it was installed. Now, today, I am very fond of using D|S. The program is a kewl utility for Bryce. I am beginning to like it.
