Access form design using layout - how to center controls

Hi all,

I would like to have a sort of a main menu form on my Access front end, horizontally centered in the middle of the form, no matter the resolution or window size. I can easily do it (and I did) by simple VBA executed on form_Resize event, but I'd rather know how to do it without it.

In design view, I created a tabular layout with three columns, with my subform in the middle. Now, what I would love to achieve is for the middle column to always stay the same width but the side columns always resize with the window, so the middle column is always in the middle of the Access window.

No matter what I do, I just can't accomplish to have both side columns size with each other.

Thanks in advance for any ideas.
