Will I lose my work if I change pages before finishing an activity/task log or sending an email?

Yes. If a user is in the process of writing an email or logging an activity/task in Avionté they will lose what has been written in the Rich Text Editor if they leave the page. 

However, Avionté does provide a warning before leaving the page. Users must click continue before they can switch the page. Keep in mind it will only give this warning once 10 or more characters have been entered in the Rich Text Editor.
