--- Comment #6 from Vitaliy Margolen vitaliy@kievinfo.com 2007-09-07 08:05:38 --- It seems this problem is not solved yet on FreeBSD. This is work in progress and there are several people who working on it.
There is not much Wine can do about this issue - $fs register absolutely required for win apps to work.
