Why when activate a VI window title bar the VI stop for a while

[Lili]

Why a VI in run mode is afected for 300-400 ms, by selecting another Labview window or when seleted another VI window and replaced on the screen.

[LesHammer]

Because the VI can only run when the Operating System (such as Microsoft Windows) gives it time to run. When you select another LV window or VI, the OS gets busy doing the new task. This can also occur if email comes in. If this is too upsetting then you need a real time OS.
