I don't know why I didn't notice this sooner, but in my Trends page the selected thumbnail does not display properly. Instead of displaying in the larger box, it goes to a new page. The box where the selected thumbnail should display is on 3/4" high by 8.5" across.
I took the trendsT.htm file from my Weather_Blues_v1 download and reinstalled it. However, I get the same result. Could it be a styles.css issue? If so, I have no idea where to look.
