Word Wrap problem in RTE Control

We have an internal use PB 12.5 app that uses a RTE control. We have Word Wrap set on, in the control.

We have this installed on 3 computers. On two of the computers, word wrap works perfectly. But on one of them, lines don't wrap unless there's a newline, and you have to scroll horizontally to see all of the text. If you right-click and pick Properties though, it shows Word Wrap as being on!

Any thoughts? Thanks.
