WindowWatch is a tool that developers and Webmasters can use to quickly preview the results of their efforts. It locks onto whatever window is currently active on your Bureau and lets you manipulate it in a variety of ways, displaying it in various screen resolutions. You can instantly resize a window to any standard Bureau Taille and modify the tool's built-in Bureau settings or add several of your own, without altering your computer's display settings. New features include active Bureau rulers with the ability to "lock" to the active window. You can set rulers to relative or absolute modes. WindowWatch also now includes a new active window measuring slider for precise control over the test resizing of your windows, screens, applications, and images.
