Hi,

Build a grid with a checkBox on Column.
Set CheckBox.Caption = ''
Set CheckBox.BackColor = 255,0,0

1° CheckBox.Alignment='left'
Column.Width =< 15
run
right columnLine is overwrite with red color

2° CheckBox.Alignment='right'
Column.Width =< 15
run
left columnLine is overwrite with red color,
but if you go within checkbox and move grid line,
overwrite not occur.

3° CheckBox.Centered=.T.
Column.Width =< 17
run
right columnLine is overwrite with red color

My problem is with 3°; for symmetric center, column with need to be odd,
then 17 is very good to me, but with bug restrict my choice to column.width>=18, and for get symmetrix position to >=19.
