Main menu panel corrupted.
This morning I've launched 64studio to find that my main menu panel seems to be not working. Firstly, it gets displayed at the top of my screen (previously, it was always at the bottom). Secondly, there's absolutely nothing at all shown in the panel. There's no actual menu (i.e. for launching apps) and no icons get displayed. This means that I can't even shut down my PC without physically disconnecting the mains. Can anyone think what might have gone wrong?

Thanks
