Can a user who is connected to the system from one computer log in from another computer?

No. If a user has logged in from one computer and simultaneously attempts to do the same from a second computer, a pop-up window will appear indicating that the user has already logged in from another location. To log in from the second computer it is necessary to log out from the first one as follows:

1. In the main menu, click Exit.
2. In the pop-up window, click Yes.
