This morning when I started my Ubuntu, a notification appeared that say something like:
The windows applet is not working, would you like to delete?
I was in a rush and just push delete. *ups
The result is when I minimize any program, its indicator wouldn't showed up in the bottom most bar (I'm not using Unity btw, I'm using Gnome Classic).
Is there a way to install the applet back again? I was trying the synaptic manager but didn't find anything close.
