--- Comment #1 from Alexandre Julliard julliard@winehq.org --- What has changed is that builtins now require the actual file to be found to be executed. Since Wordpad is not in the path (it's in Program Files\Windows NT\Accessories) you have to specify an explicit path now, like you would on Windows.
