So from all my research from this forum, I've came up with pretty much the same algorithm written many different ways -- all are yielding the same, yet wrong, answer. My example: I want to click on a certain button with MouseClick. It is located at 885, 183 (we will just use the x coord for demonstration) with the resolution of 1440x900. I want to be able to click on that same button (it's very small) with a 1280x720 resolution as well. So, I plugged in 885 in any of those 3 equatio
