Floats don't seem to work correctly on Mozilla (haven't tested IE). The prev button stacks ontop of the next button. All that after struggling to apply the float style, because you can't do obj.style.float = 'right'; instead you have to do someOtherObject.innerHTML = '[a style="float: right"][/a]' (this comment system tends to mess up angle brackets, so I replaced those with square brackets). Floats seem really unreliable to me. And I still have to work on the events.
to bad I can't edit my posting:
sorry for double posting.
