Comment 65 for bug 729979

Found a solution, which is crappiest but... use the horrible Unity
switcher, I was using Compiz Ring switcher, changed back to Unity and
now the problem doesn't occur. I needed something with a app preview but
I guess I'll have to conform to the Unity stuff.

As a palliative I created a launcher on the dock for Scale, so I can
click and see all windows, check if the processes I'm running are over
yet or not, and then keep working. Not the best, but endurable.
