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.
