Added: After looking at the code you posted above, I can see the problem. After calling Show(), the method ends. The variable referencing your form goes out of scope and gets recycled: your form is not getting a chance to render before it gets disposed. If it absolutely has to be modeless, you will need to move the scope of your form's variable out.

   private Dictionary<string, ChatMessageForm> chatMessages = new Dictionary<string, ChatMessageForm>();<br />
...<br />
     string message, sender;          <br />
           message = "blah";<br />
           sender = "me";<br />
            if (!chatMessages.ContainsKey(sender))<br />
            {<br />
                chatMessages.Add(sender, new ChatMessageForm(sender));<br />
            }<br />
            chatMessages[sender].ShowDialog();}

//...
public frmMain()
{
   InitializeComponent();
   frmMain.Click += new EventHandler(frmMain_Click);
}

ChatForm frmChat;
void frmMain_Click(object sender, EventArgs e)
{
    if (frmChat == null)
    {
       frmChat = new ChatForm();
       frmChat.Show();
    }
    frmChat.BringToFront();
}

//Cisco event handler (can't rem it's method def)
...
{
   InvokeMethod();
}

private delegate void EmptyHandler();
private void InvokeMethod()
{
    if (this.InvokeRequired) // 'this' is frmMain
        this.Invoke(new EmptyHandler(InvokeMethod), null);
    else
    {
       ChatForm frmChat = new ChatForm();
       frmChat.Show();
    }
}

I was wondering if it was possible to eject USB and CD roms drives of a remote computer?

I have seen code out there for local machines, but nothing really remote.

It also makes the code more readable.
