When users check in files by using Check In from the context menu, the Check In dialog displays. By default, this dialog allows them, but does not require them, to type a comment about the operation.
or selectingIf users check in files by clicking either of the Check In buttons on the toolbar, this dialog box does not open, so they cannot type a revision comment.

The Properties dialog box opens.
From this time on, the Check-in dialog box will always open when users check in files, and they will need to type text in the Reason for Check-in field before completing the operation.
