SYMPTOMS
========

A Visual Basic project crashes with an Invalid Page Fault (IPF) when you try to
call the PrintForm method in a form containing a UserControl. This behavior
occurs when trying to print to a postscript printer from Microsoft Windows 95 or
Microsoft Windows 98. The error message is similar to the following:

  This program has performed an illegal operation and will be shutdown.

Clicking on Details may reveal text similar to the following:

  VB6 caused a general protection fault in module PSCRIPT.DRV at 0004:00000020.

This problem does not occur on non-postscript printers.
