I found the preference. MY problem seem to start when I tried to fix another problem. You know that little oblong box on the right side of the screen, where just the title of stories are posted? Something happened, and only a fraction of that box was showing when I was looking at the thread titles. I had to use that little blue arrow on the bottom to make it slid to the left where I could read what was written there.
Is that any help...or just more confusing?
