...cycle the power!

Apparently, the act of taking the battery out of the remote, walking it over to the Wal-Mart jewelry counter, and testing it (it was still good, of course) fixed the problem. Either I scared a charge back into the battery, or it gave the remote time to reset something in its innards. Either way, I'm back in business.

Kinda reminds me of this story.

Thanks to all who piped up with help!
