In InterTest/SymDump 10.0, CAIN4566 COBDEMO ENTRY FOR USER .ALL NOT FOUND IN TABLE is issued to ENTER R to the breakpoint in STATUS display while the session is active.
In InterTest/SymDump 9.1, no CAIN4566 was not issued and the breakpoint is marked as REMOVED.
The behavior change is actually that InterTest no longer erroneously informs the user that the monitoring entry has been removed. That is, this panel in 9.1 is incorrect, as the session still exists.
In some sense, no longer erroneously reporting the monitor session as removed is an improvement. (The session is not removed nor can it be, which is what message CAIN4568 is saying.)
