ActiveWords work everywhere, even at the Windows Desktop and in other contexts where there is no active text cursor.
Windows and some programs don't expect this and play a default sound when you try to type where there is no cursor input.
To turn this sound off (it can be really annoying!):
- On Windows 10 search Settings for "Change System Sounds." On Windows 7 open the Sound Control Panel.
- Scroll to and select "Default Beep" in the Program Events section.
- Click the "Sounds:" pull down arrow, scroll to the top, and select "(None)."
- Click "OK."
