Description:
What causes the below "Restore Previous Session" screen and how do you suppress it?

Solution:
This can happen when a connection has been terminated unexpectedly, for example when an erwin session crashes or after a loss of network connection. To suppress this message, you will need to delete all sessions from the session manager in erwin (File -> Mart -> Session Manager). You can use the keyboard Shift/Ctrl button to select multiple sessions at a time.
