Gnome-> program minimizing problem
 

I've started using Gnome 3 weeks ago and i have the following problem; when i press the minimize button of a program, the program instead of being placed down on the panel, "disappears" somewhere to the down right of my screen. However, the program does't really disappear, because when i "ps -A" on the command line a dozen of "Nautilus" and "Epiphany" programs appear, probably the ones that i had minimized a while ago. What can i do?

Are you sure you've got a panel with the window list?

I don't know what exactly do you mean with "panel with window list", but i have to add that in fact a few days ago everything worked fined. I must had done something wrong with the panel, with knowing it.
