Comment 7 for bug 612327

Here we go ;)

In this video. I opened two apps. A(chromium) and B(system-monitor). B(system monitor) had the focus. I clicked on the workspace switcher and then selected workspace 2. there opened app C(banshee). again clicked on the workspace switcher and selected the app I wanted to focus. in my case I clicked on chromium and it came to focus. then I repeated all these steps again and clicked on system monitor(instead of chromium) and it came to focus.
