Should have been.  These accounts are not regular checking accounts that have many daily disbursements, etc.  They are actually investment type accounts.  The taxpayer does not use these accounts for check writing.  There are few withdrawals from these accounts.  The only way there actually wasn't funds in the account would be if the brokerage firm took them out, which I doubt.  But of course I have no way of confirming that.  The other option is that the firm's operation erroneously rejected the withdrawals.  That is possible I think.  The purpose of my question is to see if this is something people have had a problem with before with Proseries.  Because I have a serious problem with Proseries electronic signatures.  So just checking.  

I had other payments from the same brokerage firm that did go through without problems.  Not from this same account though.
