TCP/Winsock problem

[Postmodern]

I've just recently tried doing something with the Winsock control, and have come to a wall. The problem is I noticed that if I send several data consecutivly it either gets "lost" if sent to different clients or sent all at once if sent to one client. The problem: Say you have one Server and two Client forms/apps communicating via TCP. Server has an array of tcpServer controls. If I do:

...
tcpServer(1).SendData someData
tcpServer(2).SendData someData
...



it appears that only the client 2 recieved its data.

If there is only one client and what he does is .AddItem to a ListBox after he recieves something, then few lines of sending data:

...
tcpServer.SendData data1
tcpServer.SendData data2
tcpServer.SendData data3
...



turn up on the client as only one Item in the ListBox (as data1data2data3) Instead 3 different items. What I know, is that it is not the case if I make pauses between sending. (Like if I make a timer to send data every 1ms, it gets there the proper way.

My question: Why? How do I fix this? What did I did wrong?

Anyway, I have found an answer on http://support.microsoft.com/support.../q245/1/59.asp that it's a bug and it was fixed in SP4.
