SYMPTOMS
========

When using the RichTextBox control (richtx32.ocx), setting the Font property
will cause the following message to be displayed:

   Run-time error '438':
   Object doesn't support this property or method

This behavior occurs when a RichTextBox is placed on a form using the RichTextBox
Control (RICHTX32.OCX) that comes with Visual Basic 4.0 and subsequently
executed after the RICHTX32.OCX file has been upgraded to the one that shipped
with Visual Basic 5.0.

STATUS
======

beginning of this article. This bug has been fixed in Visual Studio 97 Service
Pack 2.
