I've purchased object dock plus and was using it with Windows XP SP2. When ObjectDock is loaded, Internet Explorer locks up and locks ObjectDock. The only was to release this is to wait and click the close button for IE, or use task manager to shut IE down. Called Tech support and the said to save my current dock, remove it and start again with a default dock with no additions or docklets. Same problem. I know it was only $20, but I feel like I was cheated. This product is obviously not that stable.
