resize toolbar button

[Keepontrying]

Hello,
Using the MS ActiveX toolbar, we are trying to autosize the toolbar buttons so that each button will have it own size base on the image and caption.
Currently if we insert a button and for the caption "Favorites" and insert another button and the caption is "Find" the spacing is that of the largest caption. Is there anyway we can have the width of the button reflex the caption size? Any solutions or comments ?

Thanks
