Problem is somehow related to XHTML and IE9. If you occasionally serve document as xhtml+xml, document should pass validation to work in browser. I've noticed <form name="..."> in your example, but *name* attribute is obsolete for *form* tag in XHTML1.0, or maybe you have * * somewhere in your markup.
You can invoke $('myform').serialize() in debugger console at any time - this may reveal some clues. -- You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
