SMAT tab on Client Preferences dialog box

These options in the Client Preferences > SMAT tab assist in view definition:

By default, these options are cleared.

When Add All Messages to View automatically is selected, all messages in the SMAT file are automatically added to the view after the SMAT file is opened. Otherwise, it opens with an empty view. Adding all messages to the view does not degrade the performance. It only changes the flags of the messages in memory and shows the first message in the view.

When Restore Last View automatically is selected, the last view definition that was recorded in the ecd file is automatically applied to the view. This might affect performance when loading a SMAT file. This happens because the entire message set in the SMAT file is searched using the defined conditions in the applied view definition.
