The specialized tools in Exact Mouse do much to grease the tracks for a variety of design tasks. We found the rulers especially useful; you can put any number of them on screen, orient them vertically or horizontally and customize scale. An unobtrusive toolbar and flexible hot keys let you magnify areas of your screen and identify colors in any Windows application as well. It would be nice to be able to copy color codes to the clipboard, though. Professional pixel pushers will probably wonder how they ever got along without Exact Mouse.
