For example at the moment I'm testing pair of python scripts in PyGTKEditor: server-side and client-side.
And when I start server there is about 1 second of delay before terminal window appears.
In that second I'm trying to switch to next window with client and "BAM", server-side is full-screen and I have to press dashboard button again and again.
Dashboard is for overviewing all windows and must not be interrupted.
