Margins in form items
 

Is it possible to change the margins on the items in the form toolbar
such as a check box or option button like you can change the margins on
an autoshape or text box. The problem I am having is that I am trying
to put several check boxes right next to each other, but their margins
are so big that you can only click on the last box I placed because its
margins extend over the adjacent check box? Is my only option to space
them out?
Thanks
