>I meant dropping the horizontal. I tried in a grid that does not have column header. It is a six column grid. The grid width is 379. With the total of the column widths adding to 374, the behavior you described occurred. So I took one pixel off the right most column and it worked. The new combined witdt of the columns was 373 - and the grid did not pop to left when I tabbed out of the column just before the last one.

All right, thanks
