OK, I see no hard coded events on the form in any browser, but I will just say IE 6, as that is what we are concerned with. The red parts aren't there:
So, unless the event is assigned via script, it won't happen. Further, the form does submit on enter hit in the text field in IE 6, like in this simple unscripted demo:Code:<form id="form1" method="post" action="" onsubmit="sendForm(event)">
In short, without events assigned to the form, I cannot see what you expect to happen other than a default submission.Code:<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
