YFD: click the button with a triangle, level with the word Surfaces and on the right-hand edge of the palette - select Show surface list from the menu that pops up. That will get you a list of surfaces that doesn't go away when you click on an item (making it easier to select multiple surfaces at once) as well as the Copy/Paste buttons for settings. Muller: 3Delight is the software renderer, as opposed to the hardware assisted OpenGL renderer that uses your video card. Got to Render>Render settings and drag the slider at the top all the way to the right (if it isn't already) to use it.
