       give mozilla window. showModalDialog function call compatible with ie
       fixed bug when a modal is created from a modal
       window only fires closeWindow if the popup dialog calls it, unhooked call from document.unload
       If the window reloads the close event fired, in 99% of the cases we want it when the window closes
       regardless of the windows document changing.  When the window opens the event handler is saved, then disabled
       the page must provide a way to close the window & reenable the event.
