I use the RocketDock mainly in XP over Vista even since Vista has everything stuffed on the qiuck launch bar at the moment.
That cleans up a real mess for both of those real fast!
Plus the RocketDock tool can be a real pain at times when you have an IE or other browser window open maximized and that pops up right when you are looking close by or taking a clip with the snipping tool. "rotten 3rd party annoyance!"
The one thing tried here after ticking the show on desktop for the CP was to create a second shortcut and not being able to pin that onto the taskbar and no option to unblock on either!
