Ken,

I've seen this happen after the default font has been changed for the grid. The only work around I've found is to set the column width with code (thisform.grdMyGrid.Column1.Width = 60). Hard coding can sometimes be avoided if you set the column width to something other than the default 75.

Hope this helps.
