    When I open a pdf file it is not visible. According to PDF Reader it is open because I can see the document listed it under the 'Window' menu, but it is not visible. To all intents and purposes it is not open, but for some reason the program says it is. Why?

    PDF documents I created and have opened before can no longer be opened.  I get the following caption:  

    The document “img20231224_11073442.pdf” could not be opened. You don’t have permission.

    The thumbnail of the document is visible when I select it.  Changing permissions does not resolve problem.
