DockReboot (was Dock Restarter)... You know the problem, when the Dock doesn't work anymore and you can not open an application? Then you are not alone with this problem! A lot of Mac-Users have to restart the Finder or the whole computer to solve this problem. Just launch DockReboot from your application folder and the tool restarts the Dock for you.
What's new in DockReboot
options added (Show Success Window, Ask before restarting Dock)
refresh option (if your Dock often freezes in, you can just press Command + R to refresh without quiting DockReboot)
