There are no scroll bars on any of the windows in the SYSTM app. If you do not have a trackpad or scrolling mouse, you can still scroll through the screen without the use of a scroll bar. See instructions below:
How to scroll with a trackpad:
Place two fingers on the track pad and scroll the screen up and down by moving both fingers up and down and on the trackpad.
How to scroll with a scrolling mouse:
If you don't have a trackpad on your laptop or for your desktop, the purchase of a scrolling mouse should resolve your issue. (~$10 investment). You may need to set up your mouse for the scrolling in your settings. The wheel on your mouse will scroll the screen.
How to scroll using your keyboard:
Select the screen that you want to scroll (background of the screen is where you want to click), and then scroll with the up and down arrows on your keyboard.
