when ever i open my laptop( lenovo ideapad z510) the 1st icon remain selected and every time i click on something else, 1st icon open. it seems like mouse pad is stuck or something. it happens with pdf or webpages too, it get stuck at the top, even if i forcibly try to scroll down it goes up.
It started happening few days back after there was an update to my current windows 10 OS . so i removed that update but problem persisted and later i degraded back to windows 8 and then upgraded again to windows 10, but still facing the same problem.
when i press tab or windows key the problem remains dormant for sometime and everything start functioning normal but after 5-10 mins. it resurfaces again.
with exams around the corner its really frustrating.
