#define TCPIP_MBOX_SIZE (sizeof(void*)) It's a little strange: in this case, on a 32bit target, you have TCPIP_MBOX_SIZE = 4 which is too small to my point of view. Can you test to increase it ? ==================================== Frédéric BERNON HYMATOM SA Chef de projet informatique Microsoft Certified Professional Tél. : +33 (0)4-67-87-61-10 Fax. : +33 (0)4-67-70-85-44 Email : [EMAIL PROTECTED] Web Site : http://www.hymatom.fr ==================================== P Avant d'imprimer, penser à l'environnement
