I need help...


I have problems during the installation of another software and playing some games.
The mouse stops and I can´t move the cursor or click...and I´m quadriplegic, so I need someone by my side everytime I go to install programs...
I try changing the configuration in user accounts but nothing...
And in games the same problem, the cursor doesn´t move... and I need move to click in windows screen keyboard.
So...somebody can help me?
I use a SmartNav 4 in Windows 10 (but this problem I had in Windows 8.1...not in XP)
Thanks!!
