I'm running openSUSE 11 and KDE4. I did something, I don't know what, that caused the panel at the bottom of the screen to disappear. I thought I had found a way to restore it, but now when, from the panel, I select "help" and "about KDE" or "about KDE Panel" it says the version is 3.5.9. How can I restore the 4.0 version?

Thank you.
