Hello everyone,
Rant to follow. So, IdleSaver stopped working with no apparent reason. First tried changing lots of settings in Process Lasso, even resetting them to default - to no avail.
After some research, I unearthed an ancient Windows issue, which for some reason will disable Power saving/screensavers etc. if you simply have a USB Joystick/Gamepad connected.
I then remembered recently removing a couple of joysticks from the USB Hub and connecting them directly to the PC. Long story short: disabling the joysticks automagically restored IdleSaver operation (using USBDeview as described here (https://answers.microsoft.com/en-us/windows/forum/all/screensaver-wont-work-in-windows-10-with-game/752b86d4-12f1-4649-b6d9-fb605e7e6766?messageid=9f95ada4-b778-4f10-9da8-ebe8fbd89eec)).
Why aren't they fixing this after all this time? Unless there's a reason for USB Joysticks to always keep the system alert? :o
