Javascript alerts versus popup windows

for

We're working on a web-based application that will be
used in an intranet situation, where we can specify
that users use newer, JavaScript-enabled browsers and
assistive technologies.

In some areas, we want to give the user an "are you
sure you want to do this" type of message when they
hit submit buttons.

Sometimes, this message is simple. We can use a plain,
simple JavaScript alert for these.

But other times, the message has a lot of information
in it that would be more readable if it was
HTML-formatted. Since we cannot do that in a
JavaScript alert, we would need to do it in a popup
window (window.open), instead.

My question is: is there any difference in support,
among assistive technologies, for the JavaScript alert
versus a popup window? Any difference in
accessibility? Will people who are visually-impaired
or mobility-impaired be able to handle JavaScript
alerts better than popup windows?

Thanks
Rachel Sengers
