When creating a simple document, when the text reaches the end of a line,
instead of keeping a word together, it just stops where it is in that word,
and continues the same word on the next line, like this:

managed retained collections, cleaned and reasse
mbled fragments of various items, performed var
ious ......

I've already checked for hyphenating, and it's turned off. What's going on,
and how can I fix it?
