I'm not sure, SysMetric(5) [Width of Scrollbar Arrow] returns 16 but my excess on the column.widths is 36. Comes a long way short. I've decided to use 36 for now and see what happens when other grids begin to use the functionality I've added in (to resize the form to show all columns in the grid - child form).
