I just wrote a trivial D5 app that has a form
and writes 5000 lines to a memo control and then
closes the main form (terminating).
Not sure if this is a good simulation of what your
app does - but if i start this and then "lock" my
workstation - this app continues to run (writing to
the display even though i can't see it) and then
exits. It doesn't "hang" until i unlock or anything
like that.
So - if locking does impede apps that want to interact
with the display it seems it impedes their STARTING
some way, but doesn't stop them from executing.
I don't have norton schedule (unless maybe its in the
NAV somewhere) so i can't try that test.
