Hello Valentin, >Privet! We've solved this problem by letting everybody run applications tru the "luncher", a special program which check a date and time of executable on network drive and if it's newer than existing one it copies a new one to their local drive and It is another problem which belongs to networked application. And he (the author) does want to have small patch file instead of sending a big new executable over the WAN (or modem). I know this PITA! ;) >Sorry for my English. I speak Russian and so do you. Ah, no problem, I'm trying to improve my English (especially, spoken) and also trying to not forget Russian < g
