Well, an update, of sorts.

The window issue seems to be resolved; many thanks on that. The colour picker for the lights is doing more odd things than I thought: it's almost like the entire spectral chart — on both sides — has been reduced to a giant grey scale. The lights go black when I'm on the left side, but they go progressively lighter (albeit in grey tones) as I move left. But if I use the thing in the upper right, that takes you to various colour methods, then it works. And I was able to cut down the harshness by unclicking displacement maps in the Firefly settings.

:: sigh :: New software. such a pain in the beginning. Usually so worth it once you figure it out. :-)
