I’m unable to display the whole Facebook “Send” Button in IE7.
However, It’s working fine in Chrome, Mozilla, IE9, IE8.
The Send button layout become:-

my HTML code as:-
<div class="facebook_wrapper">
<script src="http://connect.facebook.net/en_US/all.js#appId=119279021491995&xfbml=1"</script>
<fb:send font=" " href="http://www.google.com.my/"></fb:send>
</div>
Alright, lets see if I can get this right for you, since you aren’t dropping IE7 support.
P.S. I have no way to test this, because the developer tools on IE9 don’t show a problem when trying to view it as IE7. Hope this fixes it!
EDIT – If the previous doesn’t work, it would appear that this problem could possibly be due to other styling that is still be applied.
