This dialog box appears in situations like these:
Anytime you delete something or remove someone.
If you will import a file that will overwrite data.
When you filter a discussion to confirm that you want to save the filter as a default for the step (Admin when online).
It can appear differently and may or may not describe what you will delete or overwrite. Typically, you can click No to cancel or Yes to continue.
A unique version of this dialog box is opened from the Spell Checking Languages dialog box:
Restart will close and restart Audio Project Manager Desktop.
Close will save your changes so they will remain as "pending" until after you log out, exit out of the program and log in again.
