A reminder of the importance of opening Dragon first, before other applications. This is particularly important for Microsoft Office applications (Word, Outlook , Excel, PowerPoint, Teams) and web browsers, to ensure that the add-ins and extensions are loaded.
It is also important to close Dragon before shutting down your computer. Say "Exit Dragon". If Dragon is open when you shut down, there is a risk of damage to your user profile.
While on the subject of shutting down your computer, it's important to do a proper shutdown each day and not just log out of windows, or close the lid. RAM is flushed when your computer is shutdown or restarted (this doesn't happen if you log out of windows), meaning more RAM available for Dragon. If your computer is not very high spec, you could consider a restart at lunchtime - but don't forget to close Dragon first.
