Somewhere along the line, some PC performance app altered how the "Show Desktop" button in the bottom-right of Windows 7 works. By default, it takes a second to activate when you hover over it. But now, the exact moment I hover over it, the screen goes blank, and it's quite annoying.
The tool(s) which most likely did this was Advanced System Care (and its multiple additional apps). I'm guessing there may be a registry setting somewhere I can tweak to fix this.
How can I revert this particular setting so that the desktop doesn't show the exact second I hover over the "Show Desktop" button in the bottom-right of my screen?
