[Tom Goddard]

The user clicked on a file history thumbnail of a session and the session restore failed when it tried to reset the current session which resulted in closing the currently opened models. Closing a currently opened model failed because of some inconsistency in the atomic structure graphics updating code. That inconsistency was almost surely caused by a previous error before the session restore. But the Log appears to have been cleared so there is no record in the bug report of that previous error.

The daily build used in this bug report was made one day before code was added to avoid clearing the log during a session restore.

[Tom Goddard]

I could add code that ignores the inconsistent graphics updater state where it appears a structure was being removed that was never added to the session, or was being removed twice. But it is important to catch those errors as soon as they happen so I will leave the code as is. Will fix the primary error if it is reported again with adequate log info.
