After ValidatorCommonOnSubmit(), the next step for the javascript is to run
the <form onsubmit=> event. That code tests if Page_BlockSubmit to determine
if it should stop. There is a bug in earlier v1.1 net in this place, where
it doesn't use "return" to return true or false. This breaks IE/Mac for sure
and may be affecting you. There is a hotfix for v1.1 ASP.NET located at
msdn.microsoft.com. I don't know the KB article number.

Also just look at the code for onsubmit. If it involves other code than
validation, a javascript error in that other code may stop the script from
executing, and keep the page from submitting.
