Hy, I didn't have any problems with iframe (except on facebook apps developped for security reasons, not the problem). I change an option on google chrome some days ago: I think it was something like authorize iframe from other domains (a cross-domain so). Since, any iframe can load even in firefox. I try to find again the option on chrome, but it has disappeared (without update I think) I verified global internet option (windows 7) and check iframe cross domain option, even with this I can't load cross domain iframe, even if I create en html doc with the code: <iframe src="http://www.google.fr" width='100%' height='200px'></iframe> no option on firefox (aurora by the way updated).
