Can you provide the sequence/steps for this problem? I tried having 2 instances of IC8.0A open, one with Edit Items and the other with Enter Receipts. I created a new item in the first, then went to the 2nd and entered and posted a receipt for that item - without locking messages. I tried this with both instances having the same Adagio user login and also with different logins.

What version of IC80A is in use, and are they entering Item Notes? Are they copying or deleting items?
