Le problème est when, pour une raison quelconque, I accidentally Right-Alt Right-clicked an icon in la barre des tâches. And that causes to freeze the highlighting on any icon that is selected from la barre des tâches. J'ai réussi à solve this by:
1* Faites un clic droit sur an icon on la barre des tâches. (nothing will happen, except that icon highlight sticks). 2* Press the WIN-Key. (opens the menu Démarrer + the context menu for the previously Right-clicked icon).
This problem is not new to me as it occurs when I was using [Windows 7 + Windows 8.1], and Found a solution that worked with the both OSs: (Shift-Right Click). But in Windows 10 that is no more applicable. Je ne sais pas but Je pense Microsoft is keeping this bug as an evil-eye protection, this is the 4th OS upgrade and the bug still exists.
Je ne trouve pas any solution for this in the internet pages. Toute aide is highly appreciate it because this thing is really frustrating.
