Holes in the scroll bars of form control list boxes
If you go to the Developer tab and, against a coloured background, insert a list box from the Form Controls, you will see a transparent 1-pixel strip on either side of the list box's scroll bar.
This issue arises when you make a "pseudo-form" using form controls and shape objects grouped together.
It's not visually appealing. Please fill these holes.
