The following message pops up immediately when the main page in Lotus Notes comes up. I am not able to navigate at all from the main page. No e-mail list comes up. I did upgrade to Firefox 4.0.1 and have disabled pop-ups. I've seen many posts about this but theones I've seen have been outdated. Not sure if any updates on this issue are available since 2009.
