Re: Javascript Rollovers and accessibility

If the rollovers are only for presentation affects then accessibility is not negatively impacted. The problem we had was when web designers used rollovers to add buttons to graphics. people navigating with the key board was not able to bring these additional selections up. The weather.gov site is still using rollovers for changing colors. The screen reader ignores this feature.

Generally in my experience, the rollover effect has been nothing more than for presentational effect, so anyone with javascript turned off or didn't support could still click the link, or navigate to it on a keyboard and access the information behind it, and would ignore the onmouseover/onmouseout, and onfocus/onblur events.
