exec system passthru

Sorry if question was asked, but i did not find any information I use Apache/1.3.20 Win32 PHP/4.0.5 on a Windows ME I can run commands built in command.com like dir or cd, using system() or passthru(), but whenever i try to use external command, like pkunzip or gzip, the web server hangs and i have to restart my computer The only solution i found was specifying the commands in a .bat file and running the .bat file with system() - which works OK Someone had the same problem or a possible solution tahnks ---------------------------------------------------------------------------------- Visit our site at http://eshop.bg
