I have this code on an exit button and when I hit the button and select 'yes' to save the data I receive the figure again. Why? What am i doing wrong? And why when I select 'no', I receive the questiondlg again?

    answer=questdlg('Save changes to the model?',...
            'Exit ADADCS Confirm','Yes','No','Cancel','Cancel');
             switch answer
        case 'Yes'
           [filename,pathname] = uiputfile('default','Save your GUI settings');
if pathname == 0 %if the user pressed cancelled, then we exit this callback
  return
end
%construct the path name of the save location
saveDataName = fullfile(pathname,filename); 
%saves the gui data
hgsave(saveDataName);
          delete(hObject);% Hint: delete(hObject) closes the figure
          close all;
      case 'No'
          delete(hObject);% Hint: delete(hObject) closes the figure
          close all;
  end

I tried your code and it works without any of the problems you describe, they might be caused by other code.

Just two small suggestions, the close all doesn't need the ; at the end, it's common to both Yes and No responses (also the cancel got the return line), you can remove those two "close all" lines put it after the end of that code.
