Thank you, Midwested. I have not changed anything on my computer. Ironically, I can see the slideshow today? The only thing that I can think of is that some ads make FlashPlayer overheat my computer, so I might have had to Force Quit it for something else before I tried to view the slideshow. Most things will start FlashPlayer up again, without my touching it, if they require it. From what I have read, FlashPlayer is not considered to be a particularly safe application. Knowing that the slideshow runs in it, I will make sure that FlashPlayer is running in the future when I want to see the slideshow. I would have thought that there would have been some kind of message, but it was just a totally blank window. Other things that require FlashPlayer tell me that it crashed after I ForceQuit it. Thank you for the heads up. :-)
