Lenovo z710 Clickpad/touchpad rightclick ? question

Hello,

I got maybe "silly" question for owner's lenovo z710, but i get my laptop from fiance and she can't answer my question, so i ask here,

How this touchpad(TP) works. If i click left side of TP this point file, if i tap 2 times of all space this open file, but if i click right side/corner of TP this open context menu of file or desktop etc. This should works like that ? this right side button dont react as ppm...

I want to mention Windows 10 was upgraded from 8.1 automatically, "probablly" on windows 8.1 this button work properly

--reinstaled the drivers- dosent help

touchpad/clickpad v 8.1 seems to work normally react on any touch, i checked the software there is a option if i tap 2 times on midlle tp, context menu should appear but not.

I know there is plenty of topics but mostly touchpad there don'twork at all so i couldnt find my answer.

Thanks for any reply Greetings
