I have some pictures saved to my Desktop that I often include in emails I send out. I create the email. Then to include the picture I go to Insert and then click on 'single photo' and get a drop down box. From there I normally select Desktop and then choose the photo I wish to insert. BUT Desktop has just vanished from that drop down box. There is Downloads, Libraries, Pictures, C drive, etc BUT NO dektop option anymore. What do I do to restore that please???
