Posting this from home and can't provide the exact version numbers of everything involved, but here goes:
I'm trying to call CoreFTP in command-line mode with the -s switch via system() in a Perl CGI program. Everything works great if I just run the script from the command line on any of several computers. Attempting to run the script in a client web browser results in the CoreFTP process showing in the Windows 2003 task manager on the web server, but nothing ever gets transferred and the task (or multiple tasks if the script has been attempted more than once) has to be killed. The web server is running IIS.
I'd suspect a permission problem if the CoreFTP process didn't start at all, but the fact that it apparently starts and then locks up makes it seem like something else.
I had also suspected it had something to do with the splash screen having nowhere to appear, but the same command line works fine as a Windows scheduled task even if no one is logged on.
