If you have Addsoff or Popsoff installed see Microsoft Knowledge Article ID: Q225254, MSIMN Causes Invalid Page Fault When You Quit Outlook Express at http://support.microsoft.com/support/kb/articles/Q225/2/54.ASP for fixes. If you have McAfee VirusScan version 5.x Internet Scan installed with E-mail Scan tools enabled, upgrade your software. Larry
