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.

       Picture1.Line (0, 0)-(2000, 2000)
