When I have used rectangles it has usually been in the report body rather than the header. I place the rectangle, and then position my textboxes in the rectangle where I want them to be lined up. Once my objects are in place I shrink the rectangle so it is snug against the textboxes on the left and right sides (if I didn't already place them in the rectangle that way).

I'm not sure if I have tried this in the header, though - perhaps it behaves differently there? I would hope that isn't the case.
