Yes, I'm still using Vue6 Esprit ($$$), and I've noticed that sometimes when I apply user settings to a render, the image renders to the screen as it does in preview, showing the entire image as it goes down the screen, gradually filling in the details.  Other times, it renders from the bottom up, slowly uncovering-as it were- the finished image.  Does anyone know why it sometimes works one way, and other times the other?
