You need to download a screen plug in program which will do this for you. Try Icbar or Wisbar Advanced, both available free from Aximsite>Other Resources>Downloads>Desktop & Shell. Another freeware program is Gigabar from
www.gigabar.com/downloads, but this is a more powerful, and hence more complex program than the other two. Personally I use Icbar, which can be configured to put plenty of Icons on your menu bar and can also be skinned to your personal taste.
