There is no reason that a request to help mIRC successfully work under Wine is a bad idea, allthough I agree, it is a fault in Wine, I'm sure Khaled would prefer to see more paying customers happy for a quick fix (a switch).
This is the reason I downgraded on my ubuntu installation, even though I like the line numbers.
The reason people are posting here, is because from experience, Khaled listens to and respects users.
Thanks Khaled!
