OK, I have MacBook Pro 15.4" running OpenSUSE 11.1 through Parallels 4.0.

Using KDE, had a tile on the top left of the screen with 4 icons in it. Firefox Etc.
Wanted to empty Wastebin & clicked on the little bin icon in the right hand bar of the tile.
The Tile disappeared, how do I get it back? (I did say n00b!)

Also, when switching desktops, how do I get the cube thing to come up? Do I need to install something else?
