Receivable Aging - How to remove an entry

[M Prindle]

I have a customer that is in the list since he flat out refuses to pay 
his final invoice.  I have zeroed out my accounts receivable manually 
moving the money from my accounts receivable into a non-payment 
account.  Since I'm writing it off, how do I remove him from the aging 
report?  I have tried deactivating him, but that didn't seem to help.
