guanxiaof, what do you mean "it could not bother WINE"? Are you trying to say that the error being output isn't the main problem( or a problem at all)? If that is what you're saying, what is the problem then? Sorry if I'm misunderstanding you ( I read your reply several times ). I have read elsewhere that this problem is already covered by Catalyst 8.1 and above but those were from various forums, so I wasn't sure.
