%   Note that closereq now honors the user's ShowHiddenHandles setting
%   during figure deletion.  This means that deletion listeners and
%   DeleteFcns will now operate in an environment which is not guaranteed
%   to show hidden handles.

shh=get(0,'ShowHiddenHandles');
set(0,'ShowHiddenHandles','on');
currFig=get(0,'CurrentFigure');
set(0,'ShowHiddenHandles',shh);
delete(currFig);
