A number of problems between mIRC and Windows Vista have been identified, however, I doubt that all of them have been.
Khaled is constantly monitoring and reviewing the posts on these forums regarding features, problems, and just about anything else in regards to mIRC.
Khaled does not (and never has) stated what will or will not be in future versions, or when a future version will be out.
If you have submitted your e-mail address to the mailing list, then you will be notified via e-mail when the next version is released.
If you haven't I recommend that you do so.
If you don't want your e-mail address on that list, fine, just keep an eye on the posts in the General Discussion forum for an announcement regarding a new version.
