>Freezing columns can be done by setting the movable property to .f. and set the rezizable property to .f. too

Ko, I don't think thats what he had in mind. Freezing a column, typically means create a grid column that doesn't move when the grid is scrolled to teh left or right. IOW having 1 or 2 columns always visible.

It can be done with two grids, but its a hassle and doesn't always look right.
