A VI can be set to Show Front Panel When Called and (optionally) to Close Front Panel When Finished. This setting is found under VI Properties... >> Window Appearance >> Customize.
This would allow you to have different user interfaces for different test setups.
Thanks for the info. I have not been able to 'Play' around with it again until now. I have something working, now I need to work on sizing the windows to fit next to each other. I have done the sizing and such before, I just need to search for the stuff I have archived on CD. This might work out VERY well if I get time to do it.
