p.s. if you do use the bi ondemand trial, you can also use these switches at the end of the url if you want...
&toolbar=hide&drilldowntabs=hide&statusbar=hide&sReportMode=weblayout
e.g.
https://bi.ondemand.com/show/yourdocid?fullscreen=true&toolbar=hide etc.
for more info on what those switches do, please see here.
