WindowDetective is a tool which allows you to view the WindowRecord and
GrafPort records of any window. Once you have viewed the contents of a
certain window, you may print the data, copy the data to the clipboard, or
save the data as a text file.

Developers can use WindowDetective to aid them in their development cycle.
Are Quickdraw calls not drawing in the right location and you believe the
Regions in you application (visible, clip, etc…) are getting corrupted?
Use WindowDetective! Software testers (or Quality Assurance Engineers) can
use WindowDetective for scripted regression testing and everyday guerrilla

You can find it in the dev folder on the Info-Mac sites, or from my home
