I let my niece use my laptop that is running fedora 8. I use to be able to toggle between desktops with the buttons on my taskbar numbered 1 - 4. Now they are gone and I don't know how to get them back. So now whenever I minimize anything it disappears. I can't switch between desktops anymore and am a major newb to linux. Please help!

Which version of KDE are you using? KDE 4? KDE 3?
