a bug in combination: multiple file upload + jquery form + input hint

Hi,

I am using 3 different types of plugin to validate a form, such as below,
[url]http://lauthiamkok.net/tmp/jquery/multifiles/form.php[/url]

below is the source of these plugins,
http://www.fyneworks.com/jquery/multiple-file-upload/
http://malsup.com/jquery/form/
http://onehackoranother.com/projects/jquery/jquery-grab-bag/input-hint.html

in using 'multiple-file-upload', you can use the maxlength property if you want 
to limit the number of files selected,

<form action="process.php" method="post" id="my-form" 
enctype="multipart/form-data">
        <p>E-mail<br />
        <input type="text" name="email" id="email" title="email"/></p>
        <p>File<br />
        <input type="file" name="upload[]" id="upload" class="multi" accept="gif|jpg" maxlength="2"/></p>
        <p><input type="submit" value="Submit" /></p>
    </form>

it works fine until i have installed the other two plugins - jquery form and 
input hint. 

now, whenever after I hit the submit button, the browse button appears to be 
able for selecting as many files as you wish even though I have limited the 
number in the file input field - maxlength="2".

first I found out that it was caused by the jquery form plugin, so then i tried 
to use if condition to disable the browse input button, but it still wont work,

if($('input[type=file]').length >= 3)
                    {
                        alert('hide me!');
                        //$('input:file').MultiFile('reset');
                        $('input[title]').inputHint();
                        $('input[type=file]').attr('disabled', 'disabled'); 
                    }

and I have found that it is actually the input hint causing that!

any ideas how to fix this??

the entire code is this,

$(document).ready(function() {

        $('input[title]').inputHint();
        $('#my-form').submit(function() { 
            $(this).ajaxSubmit({ 
                target: '#output',

                // dataType:  'xml', 
                // success identifies the function to invoke when the server response 
                // has been received 
                success: function() { 

                    alert($('input[type=file]').length);
                    if($('input[type=file]').length >= 3)
                    {
                        alert('hide me!');
                        //$('input:file').MultiFile('reset');
                        $('input[title]').inputHint();
                        $('input[type=file]').attr('disabled', 'disabled'); 
                    }
                } 
            }); 
            return false;

        }); 

    });

many thanks,
Lau
