Thanks, but this isn't for adding a connector. I'm annotating air photos and on my picture, I've inserted a callout that already has a line, and it is the end of this line (the callout tail) that I want to lock. If I resize the calllout text box, the line moves and I want it to lock into place so I don't have to fix the line after making changes to the callout text box. This could be done in 2007 but not (so far that I've found

It did it automatically. Really missing this feature!

This is definitely a broken item in Office 2010 and the issue resolution not been fully answered.  In all previous versions of Office the Callouts had fixed leader lines when the text box or text area was moved around.  To move the leader you had to choose the little yellow diamond at the end.  Now, the entire shape is moved around thus rendering the callouts pretty much unusable. I have had to annotate many charts and have given up with callouts completely for this purpose.

One workaround is to create a small rectangle, give it no colours, link to a bigger rectangle with an arrow or line and create a composite shape.  This can then be grouped and duplicated on a particular sheet.  It can also be copied across documents so you don't have to repeat yourself

I too have been very frustrated by the tail of the callout moving when I moved my bubble. Not sure if this is what you are looking for, but:

1) Create your callout

2) then place your mouse within the main part of the callout so that it forms a blue square around the shape

3) Hover the mouse around the edge until it looks like a icon with 4 arrows (like a compass), click then drag the bubble to the position you'd like. This will enable the callout to move while the tail portion stays in the same position.

*Note: Its seems that if you wait to long from clicking in the bubble (to form the blue square) to moving the item, the entire callout will move. Steps 2-3 must be done relatively quickly.

I couldn't replicate that behaviour BeBe.  However quickly I go from 2 to 3 the tail/pointer/leader of the callout moves too.  I wish I had a better idea but I came here looking for answers...

In Word 2007, I could insert a callout and the end of the tail would be locked in place so if I moved the text box, the tail end would still point to where I originally placed it. In 2010, I haven't found a way to lock the tail and when I move the callout text box, the entire tail moves. This is killing productivity as I then have to change all the tails after I move the callout text box. Any ideas?? Thanks.
