Background color of tooltips

The background color of my tooltips has changed from white to black?? Where is this controled from ?

There isn’t a setting for this in Preferences or anything else within SketchUp. Try rebooting your computer and see if they return to white. Also check to see that your graphics drivers are up to date. Update them if they aren’t. Go to the Nvidia site to check. Don’t trust windows to tell you if the graphics drivers are up to date.

Thank You ! Reboot did ut.
