How can I get these fields to line up correctly?

Head out to http://countryshowdown.com/. At the very top, you'll see two fields where a user can login. In Safari it looks fine, but in IE, the Password field is a little bit above the username field.

It's a small thing, but it's bugging me and I've tried several things to get them to line up to no avail.

What am I missing? What can I do to get these to line up correctly?

Here's my html:

<table cellspacing="1" cellpadding="1" border="0">
		<tr>
		<td align="left">&nbsp;<form action="contestants_validate.php" method="Post"><input type="text" name="email" class="login_box" value="username"></td>
		<td><input type="password" name="password" class="login_box" value="username"></td><td><input type="image" src="images/new_login_button.jpg" border="0" 
		name="submit"></td>
		</tr></table></form>

Select all Open in new window

...and here's my stylesheet as far as the "login_box:"

input.login_box{
   border:0px;
  width:109px;
  height:21px;
  font-size: 10px;
  color: #cccccc;
  display: inline;
}

Select all Open in new window
