There is a problem if you try to open an email attachment that is a PowerPoint presentation if:
You are using Outlook Express
You are running Windows XP, SP-2
You have the PowerPoint 2003 Viewer installed
You DO NOT have the full PowerPoint application installed
Shyam Pillai has developed a small (128 KB) program that will correct the problem and allow you to open presentation file attachments directly from your email in Outlook Express.
