mortenm:I have the same issue and really need a solution.
As described I have an IFRAME with runs on one sub-domain, e.g. "a.domain.com". From a parent page on domain "b.domain.com" I load a cuteeditor enabled page but the HTML editor is in DISPLAY mode only.
I get a javascript error: Access is denied

Should I try to add "document.domain=..." in the ashx file?
