--- Comment #11 from Igor Tarasov tarasov.igor@gmail.com 2008-08-06 07:26:16 --- Yep, this bug appears with pathnames having space. It stops on first space and can't enter subfolders. You may reproduce this bug with:
wine start 'c:\windows\profiles\All Users\Application Data'
It will open All Users, showing contents of profiles folder.
