Think-time PeopleCode Event (EvalDoModal), but a SQL update has occurred in the commit interval

Hello.   We are seeing this error message

"Think-time PeopleCode Event (EvalDoModal), but a SQL update has occurred in the commit interval....."

when trying to update and save a Vendor with Supplier Auditing turned on.  It occurs from VENDOR.VNDR_AUDIT_FLG.SaveEdit which has a DoModal code to open the audit summary window.

Anyone have any experience with this issue?  Whether on the Vendor or anywhere else?  Or does anyone have any ideas of what some of the causes might be?  We are running out of ideas, and anyone with thoughts or input on some common causes for this idea would be verymuch appreciated.
