Right-clicking on actors has been fixed, and the patch just went up on Steam. As for the dialog being interrupted, I've never seen that before, and I just tried it and it seems to work. If you're still having issues after this patch (Build 921), contract support.  Did you get it from Steam, GOG or the Mac App Store?
what is three + one + one?
