We have one account that, when we print the A/R with Running Balances report, shows a very large dollar amount in the Beginning Balance field.  Of course, it should be zero.  The dollar amount happens to be the same as their next-to-last invoice & payment amounts.  Two questions:  why would this happen and, more importantly, how can we clear that out so the Running Balances report (and their future invoices) will be correct?  Thanks for any input you can share.
