Hi. I'm new here and new to macro/macro express. I was wondering if it was possible to do this: If a color appears on my screen (or set of colors), is it possible for a new 'reaction' or 'macro command' start up? Also If a color appears on my screen (or set of colors (lets say red)), and those colors are say an inch on my screen from where another color is (lets say blue) that another macro command would start up? Thanks Ps. For the second question, look at the example I made: X..........0 (x being red and 0 being blue, nothing would happen here) X...0 (x being red and 0 being blue, my mouse would move somewhere, or something would be typed, etc.) Thanks again.
