different heighted submit buttons in ie and ff

[johnyboy]

hi,

this page http://www.hdbatik.co.uk/ectemp/b/not-found-test has a text field and a submit button next to each other. in ff the text field and button are roughly (button seems to be 1px higher but that's ok) the same size but in ie the button is significantly taller:

ff:


ie:


how can i get the ie's button about the same height as the text field?

<ul id="suggestions">

...

	<li>
		<div>
		<h4>Edit the address and try again</h4>
		<form action="/ectemp/b/not-found.html" method="post">
		
		<p class="url">
		www.hdbatik.co.uk/<input type="text" name="corrected-uri" value="ectemp/b/asdbvnvbnvbn" size="30" />
		<input type="submit" name="go" value="Go" />

		<input type="hidden" name="uri-submit" value="1" />
		</p>
		</form>
		</div>
	</li>

...

	p.url { font-size:1.2em; }
	.url, input[type="text"] { letter-spacing:.1em; }
	.url { color:#000; margin-right:.5em;}
	.wrong, input[type="text"] { color:#f00; background:#fff; }
	input[type="text"] { font-family:sans-serif; }
	input { padding:3px; border:2px #ccc solid; }

thanks
