onresize … hasn't. It is a vendor proprietary extension (as mentioned in the explanation for the error).

This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).

Generally speaking, intrinsic event attributes should be avoided anyway.
