Dreamweaver CS3 Cell Padding in Layout Mode

Working in Layout Mode.

Create two cells of different width, fixed size.

Insert text in both, fonts are different.

Place one cell above the other.

Always too much space between adjacent cells even though the cell layout lnes are touching.

It seems as if the cells have a default padding value for text? This is never a problem when the cell content is an image.

Thanks,

Martin
