I have a form that has two horizontal list boxes on it and several buttons, two of the buttons are inbetween the list boxes.

My problem is when I maximise the form at run time the bottom list box runs over the buttons and into the top list box. I have tried all the anchors and have found that I can't get the two boxes to remain the same distance apart. How can I make them work together or how can I anchor the bottom list box to the the bottom corner of the top box so the middle margin stays the same and the boxes expand with the window?

I can get the top box to expand to the correct size and place, but the bottom if anchored to top/right/left/bottom runs over the top and buttons. If it is anchored to the bottom/right/left it remains small and leaves a large margin between the two.

Any ideas, have tride writing code for it but not quiet up to that stage

That worked there are so many features to this program I missed that one. Took a little playing about with percentages (%) but very useful. Thanks
