Thanks to this forum I was able to find out why my screensaver would never start because of my wireless mouse. I updated and downloaded the patch and it started to work instantly. But later that same night after running a handful of other applications it stopped working and the screensaver won't start. I can go and preview it but it won't start once I am idle. I know that this is a ridiculus issue but my wife loves to see all our family photos as the screensaver. Can someone help? Thank you.
