  Yep.

  Yep.  You can't see that it's the cwd, but process explorer will show you 
it has a handle to desktop open.

  Dunno, but I'll tell you something I spotted the other day.

  Copy calc.exe to the root of your C:\ drive, and rename it to 
"Program.exe".

  Fire up a recently-updated RealPlayer.  Watch two instances of calc.exe 
appear.  Close RealPlayer again.  Watch two more instances of calc.exe 
appear.

  Another un-quoted path with spaces in it.  Phj33r!

     cheers,
