Not that I know of any specific change, but
should tell you what the default window color is supposed to be, and 
breaking in the corresponding SetColor() method could help you too.

Another thing to be aware of is that COL_WHITE being 0x00FFFFFF and 
COL_TRANSPARENT being 0xFFFFFFFF are somewhat similar in that their RGB 
components are somewhat identical on the first look. The semantics of 
these two items differs a lot of course.
