Funny, this doesn't happen on my system. Maybe you can change a TestStand setting to eliminate the problem, if you do not need to use the LabView development system when running. In Test Stand click Configure (on top menu bar), Adapters, highlite Labview and click on the Configure button inside the Adapter Configuration box. Click the top button "Labview Runtime Engine" and then OK, then Done. Your Labview step will run using the Labview Runtime engine without opening the Labview development environment. Of course you cannot debug your Labview program this way. Hope this helps.
