Have you ever wondered what happened to your list box rows? You know that you have more rows of data than those being displayed... so what gives?

Well, list boxes in 4D require that all the columns are the same size. With each column being an array, that means the arrays must all be the same size. However, if your array sizes are different. 4D will only display the number of rows of the smallest array. This means if you have a 3 column list box, with column1 having 1000 array elements and column2 having 500 array elements and column3 having only 5 array elements, the list box displayed will only show 5 total rows across all columns.
