ubuntu --"flashback" app/panel "scrollbar" width? -- can it be made wider?

[bruce]

Hi

Looking over Ubuntu/flashback, I have apps/windows (panels) with the
scrollbarsidebar, and I'm tryin to see if there is any method to
increase the "width" of the scrollbar/sidebar in general?

As an example, firefox in windows has a wider side/scrollbar than
firefox under flashback.

So far, no luck in viewing the 'net.

thanks
