I recently installed Linux Mint 11 on a 9-year-old IBM-T40 laptop. After I got everything installed and configured to my liking, BAM! The desktop stopped showing me a little icon in the menu bar that indicated that a program was running. I can still cycle through my programs using ALT-TAB. But I miss those little icons.

I'm not talking about the icons that one can place on the desktop or the menu bar by left-clicking on the Menu icon, then right-clicking on a program name and selecting whether to place an icon in the panel. I'm talking about the sub bar that appears in the menu bar when a program runs.

I'm sure the fix is in the Gnome conf file, but I haven't a clue how to fix it. Any help would be appreciated.

Right click on the menu bar > add to panel > window manager

right click on panel
add to panel
select window selector
click add to add to panel

click on window selector (on current open application icon on then panel) will show a list of apps that are currently opened
