I can confirm this bug on my machine. An interesting thing about this bug is that I can't reproduce it if the formula is plain text or very simple, but I can consistently reproduce it with a more complex formula, for example: "dy over dx = lim from {h -> 0} {{f(x+h) - f(x)} over h}"

Arthur, if you're able to reproduce a bug, you're also allowed to change status to NEW. (I did it for you)
