Comment 3 for bug 1510360

OK, with the latest silo 21 i've played with it enough to be convinced the "disappearing buttons" & apps launching into phone mode is fixed.

However, i still see "disappearing app", which i have now determined is actually minimized apps show up in the spread - but do not reinstate themselves onto the screen if selected from the spread. the same applications (still minimized) do reinstate themselves onto the screen if selected from the launcher.
