Why is the size of text changing on incoming messages?

[SHAGRI83]

A friend has a new Exalt II and the incoming text messages were large and easy to read (i.e., used to fill the screen).  Now all incoming texts are quite small.  How can we change it back?

Messaging font size is on page 33 of the user manual:
