Dear Hans,

Thank you for asking; indeed the idno is key unique 1 in file.rec1 and key
unique 2 in file.rec2 and file.rec 3.

I have tested the files using different computers (at least 3) they all work
fine (sorry for not stating this in my previous request).  However, the
error  occurs and continues to occur when I use my lap top (Vista) and yet
this is my main tool to design the entire database.

Clearly, the error may not be associated with EpiData; but something to do
with my laptop (with Vista, in particular).
Are there any solutions or just ignore it?

Kind regards

Tieble
