Writing Ftp client

[Peter]

Hi,

I'm writing simple FTP client in Delphi 5 with TNMFTP component.
When I want to list ftp directory, sometimes after .ChangeDir it hangs
up - software works still, but I can't close it, and ftp functions
hangs, and I must kill process.

Is any example how to do it?
How to reset ftp connection?

I'm using OnListItem to get file/folder name.
I've tried for 2 different ftp servers and it is the same.
I've tried to setup different timeout, but it doesn't help.
