You have a great ability to find possible solutions to this problem! Changing the Font Smoothing style to "CRT" in System Preferences does significantly help the text rendering problem (after a restart of Graffle) for text without fills. However, although fonts appear much better, the CRT setting does not provide for text as sharp as it is with a filled background and Font Smoothing set to "Medium". This is the solution that I will use once I upgrade to 4.0.

Thank you very much for all of your help.
