This does appear to have affected some of us. I only get the basic text based editor on this 'puter but I have all the bells and whistles on my other one.
You can get a line break by inserting the HTML line break
< br > (delete the spaces)
You can still get bold text by inserting the HTML code
< b >
Italicise using
< i >
and still add smileys using img tags eg.
{img}/FSM/CS/emoticons/icon_smile_big.gif{/img} (substitute "[" for "{" and "]" for "}")
