You can move the pin position of your comment if the proof is still in proofing progress.
To edit the pin position:
Step 1
Click to select the pin (the pin will flash).

Step 2
When the mouse cursor changes, click + hold to move the pin into the new position.

Step 3
If the pin is a line or rectangle in shape, you may also adjust the pin size/shape.

PageProof automatically saves your new pin position after a change has been made.
