Adjusting the msoControlDropdown

Hi;

I have a toolbar that works pretty much the way I want, but I would like to
do a little clean up. A question I have is can I reduce the width of a
msoControlDropdown?

I have reduced the width of the little dropdown itself by '.DropDownWidth =
35' but for this particular control I would like reduce its footprint on the
toolbar from ( I am guessing) 90 - 100 pixels to something like 50 pixels.
Is there a way to do this?

Regards Bill
