Hi. My name is***** you for your question and the opportunity to assist.
Open a PDF in Tracker and go to a page where you want to redact something.
Click Document>>Redaction>Mark for Redaction- your cursor turns into crosshairs.
Put the cursor to the top left of the area your want redacted, hold down the left mouse
button and drag a box around the area to be redacted.
Now here's the tricky part.
In a white area of the document draw anothe box the same size as the one you just created.
Once the box has been created, it will turn black when your mouse cursor is over it.
Drag to second box and place it on top of the first box.
Click Document>>Redaction>>Apply all Redactions and you're done.
I've made an offer to connect to your machine and perform these steps for you
if you'd like.
