Hi Erich Thanks for your reply, at least I'm not the only one. I did find a workaround though, which was not to close the sockets in the OnSessionClose event but I HAD to close the socket in the OnClientDisconnect event of the Listener, before I freed the client object. It appears that when a client disconnects, the OnSessionClose and the OnClientDisconnect events don't always get called in the same order and the state of the Socket isn't always consistantly closed. By forcing a close in the OnClientDisconnect event seemed to make it more stable.
I am interested in getting this working and will help where I can, as I have based my new project on this component. BTW, if anyone is interested I have written a simple wrapper around TWSocket and TICSocket so that I can compile my project for both windows and linux (with the same code base) using CrossKylix on Delphi 2005.
