Help! The minimise all windows button has gone!

[rob_frost]

I have Windows 2k, and at the bottom left of the screen, just to the right of the start button are a few icons ( still on the taskbar). I have shortcuts of IE, MP3 player, etc. I also had a little icon that was there from the beginning, which when you clicked on it, minimised all the windows. Somehow, I have managed to delete it ( its not in the recycle bin ).

I can't find a way of getting it back. I never realised how much I use it, and its a right pain not having it. Hope some one can help

Thanks
