I'm having exactly the same problem, I just installed something via the Software Centre, now the launcher won't hide. It happens at other times too, with no explanation or reason. It makes any work difficult because it sits over the top of the windows that open using the entire desktop space. I have tried a variety of workarounds that have been highlighted for other bugs but none of them have had any affect.
