DisplayFusion Pro 11.1.1 & Windows 10 Pro.
I have the photo screensaver set to use a separate folder of photos for each of two monitors. When I click on "Preview" in Screensaver settings, it works as it should, but recently, within the last few weeks or so, when it triggers, it goes to a black background with no pictures displayed. Worked a treat for years - I haven't a clue what may have caused this behavior. Any help or hints would be greatly appreciated.

Thanks for the response. So I did as you instructed, and changed the timeout to one minute. One minute later it (of course it did!) worked perfectly. Twice in a row. If the issue recurs I'll be back.
Thanks again.
