>Also is there a way of telling the combo not to select on entry. I have tried setting the 'select on entry' property of the combo box and on the column to false but it makes no difference

I have no idea why you are having such problems with a combo in a grid. I use them all the time with no problems. In grids, there is a problem if the control is a Dropdown Combo instead of a Dropdown List. As for SelectOnEntry, remove the K from the Format property of the combo.
