[another Linda]

Got a call yesterday from Redwitch (my trusty go-to, problem-solver, Juanita-on-the-spot) saying that the people renting our place reported that our neighbor did something to her garage door opener and now ours was going up-down-up-down. The neighbor apparently unplugged hers and took off to Italy for a month leaving our door having seizures. The renter had tried switching to a different frequency but that didn't work. RW called the opener guys but they couldn't come out for several days. Luckily RW didn't immediately assume demonic possession and told the renter to cycle through the frequencies to see if any solved the problem. And they found one that worked. So for now the evil spirit has been exorcised.

But now my question ... what on earth is going on here? Has anyone else had a problem like this? Will the evil spirit come back? Do I need to add demonic possession of garage door openers to my list of fears?
