Dang. Wasn't aware of that. I certainly didn't want to feel special re: this issue. We never did look at my Method QB Sync. settings yesterday but there's nothing special there, I don't think.
One thing I noticed in my AuditTrail immediately after the record update goes through (the record with blank values) is the message below. The computer making the change is the computer the QB file and sync engine is located on.
The DesktopSync Engine modified the SalesOrder transaction '52691...', which was modified in QuickBooks on 12/6/2012 10:30:50 PM.
Let me know if there's anything else to check on my side.
Thx again
