In my Ubuntu 12.04, my mouse pointer gets stuck often. I'm talking about the touchpad and not the external mouse. The first thought would be to check whether we have given the option to lock the touchpad while typing. But, my pointer (touchpad) gets stuck simply often. The slightest of deductions I have been able to make is that this happens sometimes just after using the touchpad scrolling.

Can this problem be rectified or should it be reported as a bug?
