When you say "this macro", did you intend to post a sample or something? Not sure I can help w/ out that.
But I can offer a caveat. I have a dual monitor setup and, while trying to get my macro to recognize a certain shade of gray, I found it ran ok on one monitor but not the other.
Turns out I had 24-bit color on one and 16-bit color on the other. Two different color palettes meant that what looked like the exact same gray was actually different. Even when I attempted to copy parts of an image to the second monitor, if the gray was not in the palette of the lower bit-depth monitor, it had to choose a close approximation, but obviously with a slightly different hex value. So testing for color equality didn't work.
So be careful out there.
