Changing the settings to get "the cool background and button locations" is done under options and then under the skin tab. You have to have other Dashboard skins installed to choose from. You can download a bunch from
www.wincustomize.com.
For removing it, it can be a little more than doing the typical remove program way depending on what version you have installed. See if there is a Dashboard Helper program listed in your programs section. Use that if available. Other wise you may keep getting a file busy error.
Go to
www.snoopsoft.com and check their FAQs. They have a detailed explanantion of how to uninstall the program.
