When using the specification designer (for Checks, Invoices or Statements) I find I cannot select a field that is inside a shape such as a label inside a rectangle.

The only way I have found is to move the rectangle out of the way, select and change the element inside it and then try to get the rectangle back in the correct place again.

Selecting the rectangle and then "return to back" has no effect.

Is there another way to select elements inside a box?
