turbuiance, the latest mIRC version automatically splits a long line of text into many chunk of sentences for you if it becomes too long. You can disable the function via mIRC options under IRC Messages at "Split long channel/query message" and then deselect it, BUT you many start to see it cut off (you won't be able to see the entire message) because a text line is too long that exceeds your chat server's message length. I'll suggest that you live with the message output to preserve the integrity of it.
