Owner-drawn combo boxes, consoles in GUI apps, together in one KILLER app (literally)

The program changes your Screen of Death color theme. When I wrote this program, my main intentions weren't to create a program that changes the color theme - they were to find out how the console API functions work, and how to build an owner-drawn combo-box... The Screen of Death color changer was just the result. =) You can see both the owner-drawn combo boxes and the console window, in the included screen shot.
