the resulting patch that was attached to the bug do fix the problem. I'm not sure if the patch has been committed to CVS, but if it hasn't it probably should before the next wine release...
No it hasn't. The problem is that the fix does indeed solve the problem, but also makes the behaviour slightly incorrect. See the latest here... http://www.winehq.org/hypermail/wine-devel/2005/05/0797.html
