It doesn't work properly. The window flickers and closes itself.
If I hold Ctrl, the window with dialog appears and stays, but pressing save or open closes it.
It works fine on one condition - the JS script must be run manually by clicking on button (onclick event). Then it works ok and file can be saved,
It seems to me, that it is some security reason in IE - button can do it, but loading page can't. What do you think ? Thanks.
