Lost ability to process text modifications

Oi !! when editing my own post to correct spelling, add emphasis etc, I can no longer use any of the text display features above the edit box....cant underline, bold, add smilies etc..

Nothing so complicated. Merely had disabled scripts in my browser, hence 'onmouseover' no longer worked......humble pie here.
