On the KDE desktop (openSuse 11.2), I clicked incorrectly an "Eliminate element" option, and the task bar is not present any more; I then selected "Add graphic elements", and the most similar widget to task bar I found is "Activity bar" (translated from Spanish). I selected it and I see a big button on the pannel labeled "Desk"... If I launch several applications, I cannot see them on the panel any more... the task bar is not there...

How can I restore it?
how can elements be moved of position horizontally within the panel?
