I've had that too...but not lately
Now, as I begin to report a glitch, NATURALLY it DOESN'T occur here, when I'm reporting it. Never the less: in my first post/reply of the day, I didn't get either font/formatting options, OR the option to pull-down/legnthen the reply window.
However, NOW, as I'm typing this, I DO get those features, so I don;t know what to think (is it because I'm on dial-up?). So: just reporting it incase anybody else encounters it.
