Thats a good point, but is that not convention only? Its not required behaviour.
Suppose I am on an XWindows system and I want MSWindows behaviour. That point
about  locale is a good one.  A sequence of user actions must  map to a
state-machine that finally maps  the sequence of  clicks into a particular
function such as Maximise, Minimise, etc. Maybe its possible  to load the map 
from some sort of resource.

"Windows Actions file"
  States:
        Maximised, Minimised, UserSize;

Actions:
 TitleDoubleclick
    Maximised -> UserSize
    Minimised -> UserSize
    UserSize  -> Maximised

"XWindows Actions File"
 States:
     Maximised, Minimised, UserSize;

Actions:
 TitleDoubleclick
    Maximised -> UserSize
    Minimised -> UserSize
    UserSize -> Minimised

maybe XML would be a good way to store resources.
