Title: There is a long standing bug in Windows, where the hover state on taskbar items - highlight and a window preview - gets stuck after having the computer run for a while, as if the taskbar never notices the cursor leaving it.<p>I&#x27;ve had this bug on every single Windows version since Windows 7, on every single installation and every single Windows PC I&#x27;ve used actively.<p>Along the years I&#x27;ve seen people suggest all kinds of workarounds for this, but I&#x27;ve seen none that do more than temporarily fix the issue.<p>This bug has intrigued me ever since I noticed it being consistent across versions, and most recently I checked if it still applies to Windows 10 Anniversary Update, which it does. Why is it so persistent? Why did it survive the &quot;should-not-call-it-metro&quot; changes to the explorer shell?<p>Since there&#x27;s often interesting discussion and insight on obscure bugs in Hacker News, does anyone have any insight on this? Has anyone ever debugged it?
