I just finished downloading a file using Firefox, and then the cursor changed to a closed hand and stayed like that.
I could only move the cursor around using my touchpad, but it doesn't work when I tried to click something.
The keyboard seems still work. So I hit Alt+F4 keys to kill all the open windows and restarted Ubuntu.
I wonder if there is some solution for this cursor problem?
PS: My laptop is Lenovo T400 and OS is ubuntu 12.04
