Annika discovered she couldn't scroll on my site. I asked her to try again in her comments, since I had a similar problem and it is working now, and bless her, she did. Still not working.
Ted Phipps pointed me to Kevin, who posted this fix at Wizbang Tech. Thanks, Ted and a big round of applause to Kevin!
I'll ask Annika if it is working now. I've crossed my fingers, thrown salt over my left shoulder, stroked my rabbit's foot and kissed my four-leaf clover. I would pray, but I think God has better things to do than fix Blogger templates. On the other hand, maybe that is why he sent us Kevin...
