If you try to make a copy of a user function using Copy/Paste, then ADRIFT throws a duplicate-key exception instead of adding a number to the end of the key as it does in most other cases.
Text overrides also cannot be copied, in this case popping up a message box "TODO - Function add item of type -- still has to be completed. Please inform Campbell of what you were doing."
Lazzah's right, I think the text override error was caused by the user function exception making the developer unstable.
Text overrides can be copied but user function copying throws an exception.
