Rick,
This is the word from microsoft...

FYI: A presentation saved in PPT 2000 may not open in PowerPoint 2003 due
to new security codes that interprets some of the ways that PowerPoint 2000
saves Office Drawing objects as potential security flaws that might be
exploited. The symptoms in PowerPoint are:
1) Presentation opens up just fine in PowerPoint 2000 or PowerPoint 2002
2) When you try to open in PPT 2003 you get following error message:
"PowerPoint can't open <filename> because part of the file is missing."
The workaround is to open the presentation in PowerPoint 2002 and save the
presentation with new name (forcing a complete resave of the presentation).
After this, the file can be opened up in PowerPoint 2003.
NOTE: This is actually a core MSO problem in how Microsoft Office Drawing
objects are saved from Office 2000 and interpreted on file open in Office
2003. Because of this, problems will also occur (symptoms will vary) when:
* Open & Close a Word 2000 document in Word 2003 (or save as HTML/XML)
* Open an Excel 2000 workbook in Excel 2003 (comples OfficeArt data missing)
