Thanks for the help everybody, on both how to make the Mac forget the imaginary monitor and how to troubleshoot the real but dead one.
I zapped the PRAM, and it fixed the problem. Now the Mac knows it only has one monitor connected to it. Alex first sent me the suggestion to zap the PRAM, and I had actually thought about doing that earlier, but had forgotten what keys to hold on restart. I got out David Pogue's big thick book called "Mac OS-X Leopard, The Missing Manual," but it says not a single word about the PRAM. I tried to look up PRAM in the book's index, but it's not there--not under P, not under R for Resetting the Pram, nor Z for Zapping the PRAM, nor is it mentioned anywhere in the book's extensive Troubleshooting section--in fact, I can't find a single mention of PRAM anywhere in this huge (894 page) book, supposedly written by a Mac expert. How do you figure that? So anyway, I went online and looked up how to do it, zapped the PRAM, and now all is well. Now to try to figure out what happened to the monitor that went kablooey.
