If this started after a Windows Update, check the Stardock forums. They often post specific patches for new Windows builds. To give you the most accurate solution, could you tell me: version of Windows are you running (e.g., Windows 11 23H2)? Did this happen immediately after an update new installation Do you have other UI skinning apps installed (like Start11 or OldNewExplorer)?

Buttons, scrollbars, title bars, even the Start menu could look like anything: a Mac, a Linux distro, a marble slab, or a neon-drenched cyberpunk console. It was beautiful. It was fragile. And when its core files had a problem, things got… strange.
