I was about to post a question here regarding this, when I accidentally found a blog entry with the answer.
here it is: https://blog.gilbertconsulting.com/2015/05/a-fix-for-disappearing-file-info-dialog.html
(by the way! how can I insert links in a more beautiful way?)
My colleague who works on a Mac, told me that she was missing the File Info dialog when she was clicking on it in File menu. I don’t work on a Mac, so I was using Google to find something about it. I thought it might be useful to keep the info here, if someone is looking for an answer in the forum first.
I copy the solution as well in case the link wouldn’t work for a reason:
“I’ve had a recurring problem for awhile where occasionally the File > File Info dialog box in InDesign CC gets “stuck” somewhere outside the bounds of my monitor. In other words, I’ll choose File > File Info, and the dialog box will apparently launch, because all my menu items get grayed out and I can’t do anything, but the box isn’t visible on the screen. But, since hitting the Esc key cancels any dialog box, I’m able to hit Esc and continue working.
But I need the File Info box for my work.
I discovered today that there is a file named “DVADialogPrefs.xml” located in the User Library folder in Preferences/Adobe InDesign/Version 10.0/en_US/DVADialogPrefs. (Hold down the Option key and choose Go > Library in the Finder to display the Library folder). Quitting InDesign, deleting the “DVADialogPrefs.xml” file, and restarting InDesign fixes the problem, and allows the File Info dialog box to display properly.
I suspect that InDesign gets confused about how many monitors I have, and where they are located, because I’m constantly plugging into different projection systems as I travel to do training and seminars. Hopefully this won’t happen to you, but if it does, at least you know how to fix it!

Have a great day!
