Minimize screen and its gone! Help

Gnome + Opensuse 10.3 - When I start a program then minimize it, it vanishes into the bottom right corner of my gnome desktop. I have no idea how to get it back up again.
I want it to minimize onto my application bar (panel) so I can then click onto it and have it appear up on screen again.

Any ideas?..I have spent more than an hour trying to back to the way it was and I don’t understand why it changed. Look forward to your response.

It’s ok now…got it. Right click, add to panel, window list!

You probably removed the task-manager from the panel…
