--- Comment #2 from Alexandre Julliard julliard@winehq.org --- Probably you are running your app from the shell, so it inherits the current directory from there. If you want the cwd to be the app dir, you have to set it explicitly (cd MyWineBottle/drive_c/MyApp; wine App.exe). I expect that you'd see the same thing on Windows if you run it from the command line.
