Installed recently, and after installation the UI launched, I set up some of the cool tools, and it seemed to be working. Later I went to try to launch the configuration UI again, and nothing happens other than a brief "working" pointer.

SOMETHING is still working, because the windows snap to the edge of the screen. But the reason I want to buy this thing is to restore window positions after Windows randomly decides to rearrange them on resume. Can't access this feature.

Rebooted, installed .NET 4.8.1, rebooted some more, restarted DisplayFusionService, reboot some more, all with no effect. Task Manager shows DisplayFusion, DisplayFusion Hook App, DisplayFusion Hook App (32 bit), and DisplayFusion Service.

Windows 10, fully patched.

Yes, thank you, Owen!! The same window that I had pinned to my taskbar opens, but I guess it just won't open from the taskbar? Anyway, I unpinned it and will just open from the system tray.

Nope, I tried pinning the settings window after opening from the system tray and the same thing happens trying to click the pinned icon. Just a brief "working" cursor then nothing. But thank you again!
