Hello,

i want to write a script that open a chat window and send a message to the window.

function OnEvent_Initialize(MessengerStart)
{
Messenger.OpenChat('kassaidani@hotmail.com');
ChatWnd.SendMessage("message");
}
function OnEvent_Uninitialize(MessengerExit)
{
}

The debugger says that ChatWnd is not defined. What can I do?
