http://support.microsoft.com/default.aspx?scid=kb;en-us;305117

here is a quote from it: (do any of these things apply to you?)
"This problem may occur if you use desktop content that turns on the Active Desktop feature. For example, this problem may occur if you have a background item or desktop item that uses a transparent image or an animated GIF image, or if you set a Web page as the active desktop. This problem may also occur if you turn on the Lock Web Items on Desktop feature."

The site also gives you a solution to the problem. Try it ok? hope that it will help
