--- Comment #1 from Andrew Nguyen arethusa26@gmail.com 2011-06-23 23:03:06 CDT --- Notepad is really supposed to receive a Windows path in the command line, as it's interpreting the slash and character at the start of the Unix path as an option. I notice that notepad on XP doesn't munch option characters that it doesn't recognize, so I suppose there technically is a bug here.
