Bryce, Poser, and several other graphics programs started as MAC ONLY. There are many video editing and screen-writing programs which started the same way. My 5th computer was a Mac, and I wished that I had switched years earlier. I have also used graphics programs on the C64 and various later Amigas, so have cross-platform experience... and will say this, each platform does certain things well. When porting an application, the developers have to balance having it work the same way vs getting the most from that platform. In this instance, the problem wasn't lack of competency, but lack of staff: the entire company was down to a literal handful of people. There is this to remember about pendulums: they swing both ways. Carolly
