Hide scroll bar in rich text box BUT still allow scrolling

[Matthew]

Is it possible to hide the scroll bar in a rich text box, but still have the text scroll? I have tried different style settings, but do not seem to be able to get it to work. Here are the style settings I currently have
   

I need this because I need columns in the text box(i.e. left, centre and right align), but did not see how this was possible in one, so used three pushed up against each other - it works great, apart from it not actually scrolling when I hide the scroll bar

Kind Regards
Matt
