This is totally bumming me out. This may sound desperate but could it be that your browser didn't really download the latest version and simply retrieved the previous version from cache? The latest version disables the Save As menu at line 97: "self.file_menu.Enable(ID_SAVE, False)" Then it enables it in the OnOpen function at line 169: "self.file_menu.Enable(ID_SAVE, True)" If the first line works the second one should work as well. But then again, nothing that should work ever does.
