Hello Kirk Quinbar,
We have an idea of what might be causing this problem. Can you confirm that the space between the words is an interval and not a non-breaking space( )? That can be done if you show the formatting symbols from the ribbon bar. If the intervals between the problematic words are not marked as dots, that would confirm this theory.
Some information on the way you are using the rich text box would also be appreciated - for example, are you using a FormatProvider or a DataProvider to populate the document?
If the problem is what we suspect it to be, we are currently addressing the issue and it will be fixed in the Beta for Q1 or some minor release before that.
Greetings,
Iva
