I am getting Scrolling Issue problem

Today, I downloaded and Started using libreoffice but I am facing the issue when scrolling with the touchpad. It is not properly working. I am using Winodws 7 (64 bit). When I scroll down it automatically scrolls up.
The second problem which I am getting is, After using it for 20-45 minutes it automatically closes without any reason. is it the system fault?
I have checked many guides on sites like how to, quora, usersadvice, youtube, etc but didn’t find the solution.
I am using this software for the first time.
Any help is appreciated.
