When you write on socket, you send something like "[0]text". The length of this example string is 7 characters, but your formula gives 8 because you add 4 to the length of the original text. Perhaps, this code tries to access past the end of the string. In other languages this could lead to an exception - don't know what happens in gambas: who knows... may be it does strange things...
