This particular VI was pretty straightforward to fix, all it took was a little scripting. Listing the BD objects revealed two, the tab control terminal and a while loop. Checking the bounds of the While Loop showed the problem. So I simply used a bit more scripting to set the Content Rect of the While loop to a finite value, and then let Auto Grow snap it to its still-huge proper value. I would post the VI, but it was disposable and I did not even bother to save it after it did its job.
