Dear Tom :
>> The first (only) thing that smacked me in the mouth from your data was a FILES setting of 5. << I never change this setting (I confess that a few weeks ago I did't know what it was for) and I never had similar problem, even in more complex app. >> As the problem occurs not on other OS and is not easily replicated it is unlikely to be the cause...but as a test, change it to 35 and if the problem goes away... GREAT! << As this setting is easy to change, I'll try ... but I don't think this will help. >> Did you run the code with SET MESSAGES ON and SET ERROR MESSAGES ON as well as TRACEing it? << Yes. But it can't help because coding is not concerned : problem happen always during EDIT USING FormName. J.M. GRATIAS, Logimatique, France
