The Contract Tools Pane Appears with Black Shapes; Highlighting and Underlining are Misplaced
What this means: Most likely, the scale of your computer’s display has changed since you signed in to Windows. A Display Settings button may appear at the bottom of the Word window when this happens.
Your display’s scale may change when you connect your computer to an additional display or disconnect it from an additional display. Also, in Windows 10, you can change your display’s scale in Settings: choose Start > Settings (looks like a gear) > System > Display, and then use the “Scale and layout” controls.
To make Contract Tools appear as expected when your display’s scale has changed, you must sign out of Windows.
What you should do: Sign out of Windows, sign in, and then start Word. As an alternative to signing out of Windows, you can restart your computer.
If your display’s scale has changed since you signed in to Windows, choose Start > Settings (looks like a gear) > System > Display, and then click “Sign out now”.
Right-click the Start button, and then choose Shut down or sign out > Sign out from the menu that appears.
If black rectangles still appear in the Contract Tools pane or if highlighting and underlining still appear in the wrong place, email firstname.lastname@example.org.
If the Contract Tools pane fails to appear, see The Contract Tools Pane Won’t Appear. If both the Contract Tools ribbon tab and the Contract Tools pane fail to appear, see Contract Tools Won’t Start and Contract Tools Won’t Start due to an Error.
