A family of Microsoft relational database management systems designed for ease of use.
After a little experimentation it seems that, if you move a control's associated label to above the control, to then increase/decrease the vertical spacing between the two via the ribbon it is necessary to select the label independently first, and then the control while holding down the shift key. The vertical spacing between the two can then be increased/decreased via the Size/Space icon in the Sizing & Ordering area of the Arrange ribbon. Selecting the control first and then its associated label while holding down the shift key or by clicking and dragging the mouse pointer over the two does not allow the vertical spacing to be increased or decreased via the ribbon apparently.
