[FSY] Stuck in desktop switcher

[Alfie]

Hi guys,

I'm currently using FSY and am quiet happy. However at random times (I
can't work out what's doing it yet) 4 transparent grey boxes come up and I
can't get rid of them. It looks like a desktop switcher app with four
boxes labeled 1 .. 4.

Anyone know how I can get rid of them?

Also, does anyone know if there are any open-source projects out there
trying to get other ARM based operating systems running on the Freerunner?
All I can find at the moment are Linux based.
