Is this a button from the Forms toolbar--or an optionbutton from the Forms
toolbar--or what???
If it's a button from the Forms toolbar,
rightclick on it
choose Format Control
Properties tab
check Move and size with cells
If it's an optionbutton, you'll notice that there isn't a "move and size with
cells" option under that properties tab.
If you want to hide these shapes, you may find it much easier to use the
optionbuttons from the Control toolbox toolbar.
