I am afraid that you may be right. I shall have to decide on which medicine is the most paletable.
You know I said that I am not missing any files on my Mac, well, my search tells me that but I have loads of "?" marks in the top left hand corner of some photos (which I thought indicated a Missing File), but when I click into a photo to simply enlarge it from the grid and then go back to the grid, all the photos on that page of the grid have miraculously lost their "?" marks. I do not understand that.
Thanks for all your valuable comment, Barbara - really appreciate your input.
