I'm very glad to hear that you're ok! One hand is better than nothing ;-) I
have some troubles with two sometimes... so i can imagine how hard it would
be with only one... and especially the left one for a right-handed !

OK i just tried that too on my computers XP and 2000 and it works fine as
well.
I'll update the docu asap. I'm going to toronto for a week this saturday,
i'll be back next monday.

FWI, i found this info on the web:

 Here are the values Sun uses for the os.name property to identify various
platforms: os.name
      AIX
      Digital Unix
      FreeBSD
      HP UX
      Irix
      Linux
      Mac OS
      MPE/iX
      Netware 4.11
      OS/2
      Solaris
      Windows 2000
      Windows 95
      Windows 98
      Windows NT
      Windows XP

I believe it's a good start to gather the current platforms' name.
