Thanks Al,

I've done that, and still get the failure "A machine-level exception 
occurred during execution of this statement"

I've also tried changing CONVERTER_Free to a procedure.

Time to ask the DLL owner, or any more thoughts from the Euphoria end?

I'm using an evaluation copy of the DLL, so I don't know that the owner 
will want to put any effort into supporting me at this stage. If I can 
get it working, I'm quite happy to pay him for a licence.
