>Sound like a network problem, check the W/S & server event logs to confirm.

Thanks Nelil for your reponse but I don't think so. The problem was here, on my machine. And it's not a network terminal. Just a form - till now only one - broke. A form I haven't modified for month and I've generated exe several times during these months. A form that is used everyday a time by the user.

Thank you again.
