word of caution - I was just going to try the <thing> but on right clicking the downloaded .rar (in windows XP) to do a quick virus chaeck before unpacking, I had Avast throw a wobbly complaining a bout a threat in explorer.exe ... haven't time right now to look into it further but I suggest you exercise the appropriate care with any internet downloads if you pursue this further.
EDIT - sorry, I've repeated the scan on the .rar, and Avast didn't complain ... must be some bizzare coincidence that this warning popped up just as I rght clicked on the .rar the 1st time. Anyway, better safe than sorry :-)
