------- Additional Comments From wine@deesconsulting.com 2005-02-02 09:38 ------- This bug has been fixed as of Crossover Office 4.1. I believe the proper fix was implemented in other versions of Wine shortly after this bug was originally filed, and I believe them not to have been affected since.
According to Codeweavers, the persistence of this bug in their version was caused by a mistake in their build process. I believe the cause was compiling on a system too old to properly support Wine file locking.
