Sales Order Entry: Payment tab unavailable for Check .

Hi all, 

Currently, when using Sales Order Entry, when we use CHECK as the Deposit Payment Type under the "Totals" tab, the "Payment" tab has all fields grayed out and we can not access it. The fields under "Payment" are not grayed out if we use CREDIT CARD as the Deposit Payment Type, and we would like for it to be this way with CHECK as well. We need this so that we can hold the deposits on orders for invoices, etc. How do I go about fixing this?  

Thanks,

SuryaIT
