Hi Bert,
The [Format Callout] button in the /Text Box\ tab
of Format=>Autoshape is only available with certain
callout types.
http://support.microsoft.com/default.aspx?scid=kb;en-us;211990
If you're using a 'speech baloon' type
(those in the top row of callout autoshapes)
you can get a 2nd line by using multiple callout copies.
Create your first callout, then while it's still selected
use ctrl+D to create a duplicate, move the tongue to
the location desired, set the top call out to 'no fill'
color then either manually or with both callouts selected
use the Drawing toolbar's [Draw]=>Align or distribute
(middle then center) feature to stack them then use
[Draw]=>Group to make it a single object.
========
I am trying to add a 2nd leader to a callout in Word
2002. I click the callout,format,autoshape,text box and
the "format callout" option is greyed out. How can I do
this? Thanks>>
