KDE minimized icon on panel

SUSE 11.0 KDE 4
I dont know what happened.
If I minimize an application it disappears and
does not show an icon on the “taskbar”>:(
Any idea how to repair this???
Thanks Teunis;)

Make sure you have a task manager widget added in the panel

Thank you that worked for me.
By the way do you know how to configure the taskbar
The icon’s on the taskbar are quite small?
Thanks for your advice

Right click on the panel select panel options> Panel settings
a bar will form above the panel look for Height that’s it.
