From the Web:
"Flickering" is the feature that makes the yellow boxes on the Whiteboard flash to alert you about due and overdue treatments. If you turn off "Flickering" they will just remain yellow. This can also help your computer run a bit faster.
To change the "Flickering" setting:
Go to the "Whiteboard". On the right side of the screen, you will see the "Options".
Hover over the option icons and you will see "Flickering".
See the screenshots below:
With the "Flickering" icon blue, the feature is turned "on".
Click the icon to toggle the feature on and/or off.
To turn "Flickering" back on
Simply follow the same steps to turn the icon blue again.
