>When a grid is displayed, the text in some fields are not displayed totally and you have to arrow over to the right to reveal the rightmost contents of the given field. Why don't the grids adequately size themselves to display the fields wholly?

Grid displays exactly the same column widths as you set them in Form Designer. So, you can go to Form Designer and change widths over there, or you can reset column.width properties in run-time (e.g. in Grid.Init event).
