Are there any actions in your code? A screenshot would be nice since I can't access MMF right now. I have a clue what the problem is, so I really would like to know if there's any code.
EDIT: Never mind! Thanks, found the issue, I can't fix it within the next couple of days, though. :S
The problem is that I'm reading the last line added when adding a line break. The buffer only is 1000 chars big, so if the line is longer, it exceeds the buffer. :blush:
