Apparently, something similar happened to bobvan, and Callad responded, but, no, this doesn't seem to be what I did. I did start the scene regularly, and I did use the "merge scene" to introduce Callad's new lights. The camera stayed as it should have in DS. It doesn't get to a really small postage stamp sized window until it begins rendering in Lux. The lights are wonderful, Callad, I just have to figure out how to keep the render size I want.

I would suggest changing your render setting.

Go to Render>Render Settings> and where you see Preset change the setting to what you want the size of your render to be.

I also might note, but I'm not sure if this has to do with my problem or not, that the scene was set, in Reality, to be saved to "C:" something as one of those mesh light files. I'm on a Mac, and so Reality pointed out to me that "C:" etc. does not exist. I changed the location back to /Users/mydirectory/ etc.

Well, maybe that's another issue. It was easily taken care of, but could it possible account for the postage stamp sized render?

No the two are not related.
