How to fix the anchor point of a callout?
 

A couple of days ago I "was switched" from Excel 2003 to 2007.

In 2003, when I moved the shape of a callout, the anchor point would remain
where I put it ie the line to the anchor point would adjust itself in length
and direction. If I wanted the anchor point to move too, I had to grab the
pointer line, not the call-out border.

In 2007, wherever I grab the shape the anchor point moves with the shape ie
after the move it will be pointing to somewhere else.
Even worse: when i re-size the callout, the anchor point moves too.

What must I do in 2007 to have the anchor point remain where I put it?
