Reply box sporadicly cuts out text after Submitting

[Bobele23]

I've experienced this now a couple of times. The reply box sometimes just cuts off half of the text after Submitting it. When i go Editing the Post sometimes the text is displayed correctly in the editing box, sometimes not. Whether or not it displays it correctly in the editing box after saving it and reloading the page it shows just the halfcut or after editing the old text. I'm currently using FF 16.0.2 could this be some cookie or Script not performing correctly with some Addons ?
