Sales Order Quotes considered in Credit Limit Calculations

SOLVED

We're piloting the use of Sales Order Quotes and all of a sudden we have customers getting flagged with credit limits.  We want to keep open sales orders in the credit limit calculation but not open quotes.  How can we do this?

I saw the earlier post "Are Sales Order Quotes considered in Credit Limit Calculation?" but I have no indication that DSD multi-currency installed.  Its not showing on the installed modules listing and to my knowledge are not using multiple currencies.
