title: powerbuilder: itemchanged event doesn't trigger while changing focus
body: <p>I have a master-detail window. In the detail window when I change a field and click on the master window, the focus changes but the itemchanged event of the detail datawindow isn't fired. Now I want to fire the itemchanged event when the focus changes from one datawindow to another datawindow.</p>
  
  <p><strong>P.S.:</strong> The itemchanged event is only firing if I change a field and press tab, or if I change a field and click inside a different field of the same datawindow.</p>
