Comment 6 for bug 908811

There is also problem when you open google chrome and hangouts window. Both applications are under one google chrome icon on task bar.
If you minimize hangouts window and click chrome icon on task bar - both windows are minimized. Then click chrome icon again and you will see big header of hangouts window and very small chrome window.

P.S. I enabled ‘Minimise on Click’ feature through unity tweek tool.
