Customer.Contacts and Vendor.Contacts in the UI

SOLVED

Hi.  I have a simple question that seems like it should be obvious but is actually baffling.  In the .NET API, you can access the "Contacts" property on both the Customer object and the Vendor object.  There are contacts like BillToContact and PaymentsContact.  Yet when I actually open Sage 50 US, I cannot find this info anywhere.  I open a Customer or a Vendor, and I can't find contacts on them at all.

I asked a couple accountants who use Sage 50 all day, every day for their work, and neither of them know where to find this data.  So let's say I set information for the BillToContact on a Customer via the API - where would the user expect to find that data?  Let's assume they had the Customer window open to that customer - what should they click on?

Thanks!
