I don't know if this helps or if you can help me but I have some users on a large system that have FMP Advanced Server 12. v3. When they type it's like typing in mud. If I log them in with the full access password, everything runs fine. There is nothing super special about the security I have set up. They can run all the scripts and can create records, etc. They just can't delete them. While I've been frustrated with the 12 upgrade, I've been patient. Any suggestions other than letting everyone have the full access password?
