Making the window large only limits the posibilities of having the string you are looking for cut in two, there is no real way to prevent this from happening unless you are looking for a fixed size string. In that case you could always keep that fixed size of the old window and append the new window to the old. This way if there was an intersection you have just undone it, make sure to move your position back accordingly.
