I am calling a LabView vi asynchronously very early on in my test. Throughout the test I use "set" and "get" type vi's to retrieve and feed information to this vi but when I try to perform error checking and call a message pop-up, the pop-up closes right away as if the the first button is automatically being pushed. This behaviour exists only while the Asynch vi is up and running, the pop-ups operate correctly when the vi is not present. By correctly I mean they wait for user input...anyone have a clue why this is happening?
