I'm using Ubuntu 11.10 (unity 4.24.0) and I can't seem to focus the desktop. For example, if I press Mod4+D, the window I had opened stays focused, but the image is see is my wallpaper.

If I minimize all windows one by one, the last window I minimize is still focused when the desktop finally appears.

This means I can't add desktop icons, nor use the mouse in it.

I thought about reporting a bug, but everything works fine on other computers with the latest version of Ubuntu I've used, so I'm wondering about what's happening.

Before, when I pressed Mod4+D, the Unity Top Menu would say "Desktop - File Edit ..." and I could use the desktop properly.

Thanks in advance!
