"Sadly, I'm switching back to Windows until this gets sorted. I'm fed up
spending hours trawling the web to find solutions to a problem which seems
to be affecting so many people, but to which no permanent fix looks like
being released for now.

Edgy worked great for me, even Feisty did at first. I've no idea why the
freezes started but until I know for definite, that's my Ubuntu-experience
on hold for now!!"
