Hi Scott,
A few weeks ago I noticed something unusual when stopping PowerSDR and
shutting it down that might be related. Because I recently installed a
different computer to handle Flex duties in my station I have been
watching DPC latency fairly closely on the new system to see how it
behaves. Initially, about 50% of the time I would see an enormous DPC
latency spike for several seconds when stopping and shutting down
PowerSDR. I typically ran in "safe-mode 1" with my old system, but had
to run this system in "safe-mode 2" to eliminate random unstable
behavior such as PowerSDR occasionally shutting down when exiting the
setup menu until I found the driver(s) that were causing the issue.
(Upgrading the motherboard chipset drivers eliminated the DPC latency
issue.) I wonder if perhaps you might be experiencing a similar period
of DPC high latency that is causing PowerSDR to shut down a bit
ungracefully, and perhaps without writing to the database when it
closes. It's just a thought, and simple enough to check by moving to a
more conservative safe mode setting. If you are at "Normal" try moving
it a notch to "safe-mode 1" to see if it resolves it. You might even
find it more useful to start with "safe-mode 3" and work in the other
direction to see if it resolves the problem.

Any ideas? Would resetting to factory defaults fix the anomaly?
