The information in this article applies to:

- Microsoft Visual Basic Control Creation Edition for Windows, version 5.0 
- Microsoft Visual Basic Learning Edition for Windows, version 5.0 
- Microsoft Visual Basic Professional Edition for Windows, version 5.0

SYMPTOMS
========

When using Visual Basic 5.0 in Multiple Document Interface (MDI) mode, it is
possible to display the Properties window either docked to the main window (the
default) or floating.

If the Properties window is floating and two or more controls are selected and
you change the Font property of the controls using the floating Properties
window, Visual Basic 5.0 will crash with the message:

  "This program has performed an illegal operation and will be shut down. If
  the problem persists, contact the program vendor. VB5 caused an invalid page
  fault in module VB5.EXE"

RESOLUTION
==========

Ensure that the property window is docked when changing the font property of
multiple controls. Alternatively, if the property window is undocked, change the
font properties for each control individually.

STATUS
======
