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.

The formula seems to be: total column widths+ # of columns = grid width
In my case it was 373+6=379 - and it worked - I could not locate a line or column border width for the grid. But it did quit popping left when the elements above added to grid width.
