Jack,
Thanks for the help. It works just fine terminating gracefully. The whole problem is that another program starts my application and is designed to restart it if it terminates prematurely. In order to test this feature, my application is killed using Task Manager to verify that the other program restarts it. (Blue screen time).
I talked to a NI rep and she suggested downloading the latest drivers (DMM 2.2.1 & nidaq 7.3), and I'm doing that now.
