I manage my screensavers through DisplayFusion and have installed a screensaver that I have selected to run on each of my monitors. Screensaver runs fine when the system is NOT in the logni screen. Now in the pulldown menu where I can seelct "Screen Saver at Windows Login Screen", the screensaver I installed is not listed in that menu, despite the fact it's listed in the menu above. Only DisplayFusion screen savers are listed in the login screen options.
Why can't I select my own screensaver at the login screen?
In Windows 7 my screensaver ran perfectly whether at the login screen or not.
Another good thing ruined by the Microsoft team! I enjoyed the screensaver that I had and felt secure my workstation was locked behind it. Blank screen = boring.
