The Termbases page allows you to close a termbase that you currently have open.
To close a termbase:
Go to the Termbases page in the Home view.
In the Termbases table, clear the checkbox in the Select column next to the termbase(s) you want to close.
Click OK to confirm. MultiTerm Online closes the selected termbase and removes the relevant termbase name from the list in the browse pane.
