Does anyone know if the final release of Windows Vista will include the ability to run IE in a "Legacy Mode", i.e. running IE 6 in Vista? We have many ERP applications that are unsupported on IE7 and we are looking to determine the impacts of upgrading.
Any information on this would be greatly appreciated.
The closest to a legacy mode in IE7 is the CSS compatibility mode (aka "quirks mode"). IE lets developers choose between one of two rendering modes for CSS. If a web page contains a strict !DOCTYPE directive, IE will display it in strict mode (emphasizing standards compliance over compatibility). IE7 can also display CSS as it did in older versions of the browser; this so-called "quirks mode" is used when a web page uses a non-strict (loose?) !DOCTYPE or doesn't have a !DOCTYPE directive.
Other feature changes come into play regardless of the CSS rendering mode. Some behaviors can be managed through feature control keys and URLAction flags, though it would be wise, I think, to carefully evaluate any configuration changes for security impact and risk. For more information, please see Security and Compatibility in Internet Explorer 7.
Hope this helps...

Thanks for your help, Lance. Our specific issue to date is surrounding Siebel Application, which has heavy contingency on MS IE (lots of activex components). It would be nice if there were a "self contained" browser solution that would resolve this issue. Zero-footprint web applications that use MS IE and activex are a paradox.
Thanks Again.
