How to add scroll barto multiline text box

[Long Nguyen]

(outlook 2002; sp2)
My outlook custom form has a number of multiline text boxes. A multiline
text box will not show a scroll bar until the user clicks in the control. Is
there anyway to put the vertical scroll bar in a multiline text box
(regarless of whether there is text in it) so the user is aware that it is a
multiline text box?

I am aware that there is a scroll bar control but I do not know how to use
it.

Thanks
Long
