It's also done without feedback, and an action which isn't user initiated(the 
canceling).W while perhaps the most critical for accessibility, it also is 
generic usability issues. For example, one can be reading the message box, 
and then suddenly it disappear without knowing why. The screen resolution KCM 
has an indicator which tells it will disappear unless the user selects a 
choice.

Couldn't the API be extended to have this timeout functionality incorporated? 
Centralization is good, but most of all is consistency. It would allow 
feedback to be implemented(countdown). Dunno how to do it in a API-clean way 
though..


Cheers,
