I can't seem to find a way to keep Prince from hyphenating the last word of a page. Anyone know how to fix this?

I am using Prince 8.1, text is justified, using the default hyphen dictionaries from 8.1.

Prince tries to avoid breaking the last word in a page or column, unless it would create a worse break somewhere else. However, this involves tradeoffs, and sometimes it may not produce the ideal output. Currently there is no mechanism for entirely forbidding the hyphenation of the last word in a page, we may be able to add one in the future.
