I suggested the "are you sure" because it's basically already there for other functions, which I assume means that adding it to the disconnect button will make life easier for Khaled. That cursor jump feature is something I really dislike (a personal view) because it's a bit unpredictable at times. First thing I did when I started my current job about 4 1/2 years ago was to disable it on all the machines I use at work, about 5 or 6 of them.
