It is the top line of the EBA program window. It shows the name of the program, the name of the company to which the user is logged in and the name of the currently logged in user (in square quotes) and the login method – internal or via windows authentication.
The document window displays the name of the user who currently has the document instead of the currently logged in user. If the document is in the office with several users at the same time, all users are listed in the title bar of the window.
An EBA admnistrator can change title bar content in menu Administration>General Settings>Other>Window titles.
