When using any Office application, if you request to 'Share File' the window defaults to less than 'full size' and continue to shrink each time a new person is added to the Share To list. There is no ability to re-size the window - so eventually, after adding a few names, the screen minimizes so that nothing can be seen anymore. I have run the 'Repair' option, and no improvement was seen. This phenomenon occurs in all Office applications.
