Of course it's cross-platform - that's the whole point of writing it in Java. For all that, it's a pretty good little app. In fact, it's better than most color-pickers I've tried. Though the author should correct his blurb to mention the Dock instead of the Task Bar. He is selling it on the Mac side of Version Tracker in this instance. If he knew how much such misstatements put off Mac users, many of whom are offended by any reference to that "other" platform, he'd do it PDQ. ;-)
