Unresponsive Task Bar
Yesterday, I was busy working with online routine job. I was using my laptop and I was using Google Chrome for my browser. When I wanted to click a shortcut program from the task bar below the monitor, I couldn't click it. It didn't respond. I tried to close it using the Alt+F4 command but yet it didn't respond. But the shortcut icons from my monitor are functioning. So I had to forcibly close it pressing the power button.
What is the problem? How to solve it?
