The line option is set at break but still it won't. The paragraph option is Body Text, and when I changed it to No style, there was no change.
I also tried copying another text box from another part of the publication that was working fine. When I stayed in the lines that were already there, the text moved along just fine. When I tried to start a new line at the beginning of the text box, I had the same old problem of all the letters squeezing into one line.
Thanks for your efforts! :-}
