The slideshow option in Windows Explorer no longer works on my PC (Vista Home Premium 32 bit). When I click on the option the timer shows for a couple of seconds then disappears and nothing happens. I have looked through some other similar threads but they all appear to have slightly different symptoms from me - i.e they normally get the slideshow viewer to appear with a constant Wait instruction - I am not even getting that far. As a test, in case there were too many pics or the file sizes were too large, I have created a new folder with just a small number of low-res pics but it still won't work. Any suggestions please?
