I’ve not seen this before. Installed Quelea on a new Windows 11 laptop. Was projecting a static image. Power Management caused the laptop to go into sleep mode.
I’m not sure Quelea can prevent this at all - wouldn’t this be a case of changing the power management settings, or is there something I’m missing?
I don’t recall it happening on other systems. I know other apps like PowerPoint, media players, Netflix, etc… are able to prevent sleep mode.
