Comment 3 for bug 599576

After some investigation it appears that this does still work in Chrome (perhaps someone could confirm in Firefox?)

Adding a visible submit input element makes it work in IE also - however the moment you hide the input element with CSS (because it looks out of place) it stops working.

An alternative is to bind to the enter key event and submit the form that way, however that would play havoc with multi line edit boxes such as the text editors.

I am not sure how to proceed.... suggestions welcome....
