That's part of a feature detection that is needed to avoid an old IE bug with cloneNode not working correctly when objects elements are involved.
I think it fails because on windows server activex controls are disabled by default, it is weird though as the object element doesn't have clsid so it shouldn't even try to create an ActiveX, but apparently it does. it looks like an ie9 issue that I suspect is probably related to the activex whitelist feature. Does this prevent you from running the page at all or just give that annoying warning? Is it a reasonable solution adding the page to the trusted zone? It should work as long as trusted zone website are allowed to create ActiveX. If that is not reasonable another solution if you don't plan to support IE8 anymore is to remove the old IE code using packager as arian explains here: http://mootools.net/blog/2012/08/13/optimizing-mootools-builds-sans-internet-explorer/ We need to investigate how to do a better feature detection there. -- --- You received this message because you are subscribed to the Google Groups "MooTools Users" group.
