Thanks for that Arno.

OK, I will compile ICS with NOFORMS defined, I presume that's where it
goes rather that being defined in my app.

Since this is going to go in a thread within a service app, I had
intended to create my thread, create and start the ftp server and then
block (WaitForMultipleObjects) until the FTP server reports that new
files have arrived.  From what you say, this won't work as I'll be
blocking the FTP Server.

I use my own thread class, rather than the VCL Thread class and when
executing I just sit inside a while/WaitForMultipleObjects loop until
the terminate event is received.  If I create an FTP Server in this
thread, what would I have to call to get the FTP Server to process any
requests?

Many thanks.
