The only problem that I am aware of is that XP SP2, by default, does not allow dynamic html to run locally. This really only effects the course designer when they would like to preview an html publish from their machines before placing it on the web server.Once the content is on an actual website it works fine. The pop-up blocker can be disabled for local content by going into the advanced settings in internet options, scroll all the way down to Security and check "Allow active content to run in files on My Computer."Edited By: aaron on 38299.386412037
