I hate IE so much

My form has as follows:

email
upload file (photo)
about me (text area of 500 characters)

When i load my page in IE, and enter the email address only and then click submit, i get the validation error message (please upload a photo becasue i left the file field blank, then if i enter just one character in the file field (which is all the validation asks for) the form does nothing when i click the submit button. This only happens in IE........... can anyone see why, thanks

Here is my form

<form name="registration" id="Upload" action="<?php echo $uploadHandler ?>" onSubmit="return validate_form(this);" enctype="multipart/form-data" method="post"> 
          <table width="77%" border="0" cellspacing="1" cellpadding="0">
<tr bgcolor="#D9D9D8"> 
              <td class="form">Email:</td>
              <td><input type="text" name="email" size="32" maxlength="49">
              <img src="images/info.gif"> 
                <span class="form_small_text_2">Valid email address required</span></td>
            </tr>
            <tr bgcolor="#D9D9D8"> 
              <td class="form">Submit Your Photo:</td>
              <td class="text"><input type="hidden" name="MAX_FILE_SIZE" value="<?php echo $max_file_size ?>" /> 
                <input id="file" type="file" name="file"  size="40"/>
				<a class="linksHeader" href="read_me.php" onClick="NewWindow(this.href,'mywin','490','420','yes','center');return false" onFocus="this.blur()">Read Me</a>			</td>
            </tr>
			
            <tr bgcolor="#D9D9D8"> 
              <td class="form">About Me:</td>
              <td colspan="2" class="text">

Here is my javascript validation:

function validate_email(field,alerttxt)
{
with (field)
{
if (/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(registration.email.value))
{return (true);}
else {alert(alerttxt);return false};

}
}

function validate_file(field,alerttxt)
{
with (field)
{
numofchar=value.length;
if (numofchar<1)
{alert(alerttxt);return false}
else {return true}
}
}

function validate_about_me(field,alerttxt)
{
with (field)
{
numofchar=value.length;
if (numofchar<1)
{alert(alerttxt);return false}
else {return true}
}
}



function validate_form(thisform)
{
with (thisform)
{

if (validate_email(email,"Ooops... Please enter a valid Email address")==false)
{email.focus();return false}
if (validate_file(file,"Ooops... You left out the most important part... Please upload a Photo")==false)
{file.focus();return false}
if (validate_about_me(about_me,"Ooops... About Me section must be 1 - 500 characters in length")==false)
{about_me.focus();return false}

	{
