One of the features (already in 5.7) is: "Removed the IE security warning when previewing a page locally". When I now preview a page in IE (8) the irritating IE messagebar is always showed and everytime I have to enable the scripts or activeX components... How do I switch this off then in DHE?
That feature has been removed because I figured out that the IE local security warning can be turned off only by turning off also Scripts so pages won't work :-( I suggest you to preview your pages using an alternative browser like Chrome ;-)
