Getting InContext Editing to work with IE 8
At present, ICE doesn’t support IE8 yet. It will eventually but for now if you are using IE 8 (RC1), you can still access ICE editing by turning on the compatibility view of the website you are editing. The feature is available under the Tools menu of IE8.
To try out ICE, go to: http://incontextediting.adobe.com/
To try out IE 8 (RC1), go to: http://www.microsoft.com/windows/internet-explorer/beta/worldwide-sites.aspx
NB: Google Chrome at the moment is not supported either.
