--- Comment #1 from Vincent Povirk madewokherd@gmail.com 2008-05-18 17:26:39 --- This is apparently a problem with the shortcut. The command is:
env WINEPREFIX="/home/meh/.wine" wine "C:\Program Files\Frasse and the Peas of Kejick\Frasse.exe" C:\windows\profiles\meh\Application Data\Frasse and the Peas of Kejick\Frasse.slg
The \ character is being treated specially on Linux.
