As with Toby, Marion and Evie, FE was/is my first fractal love, and I would swear that the program is almost alive at times.. but, I enjoy UF for the soft, rounded shapes and the layering.... and one day, I might even learn how to use the other 95% of the program....but i doubt it, unless someone wants to come visit and explain it all to me... I also agree with Toby re: APO.... As for XD, it seems like a Gargantuan APO proggie.. I have it, have attempted it on several occasions, but nowhere near to understanding it..... :-)
