Can't make white colors become transparent in PowerPoint 2002/XP

Problem

You bring an image into PowerPoint and attempt to use the transparency tool to make the white pixels in the image transparent, but nothing happens. You can make other colors transparent, just not white. It works with the same image in earlier versions of PowerPoint.
Solutions

• After pasting image into PowerPoint
1. Cut
2. Paste Special, As JPEG or PNG
3. Set Transparent Color now works
• Instead of Pasting into PowerPoint...
1. Paste into an image editing program (PhotoEditor, Paint, etc.)
2. Save as JPEG or PNG
3. In PowerPoint, Insert -> Picture from file
4. Set Transparent Color now works
