Blank page on IE9

Hey Scott,

We just noticed that WP-SpamShield causes Internet Explorer 9 to display a blank page whenever a comment form is displayed.

A look at the source of those pages shows that they only contain the hidden referrer field that is inserted by the spamshield_comment_form_addendum() action:
<input type='hidden' name='ref2xJS' value='…'>

This is most likely because of the inconsistent support for deferred scripts in IE, which executes document.write too late.

Was there any reason for using it in the first place? Removing the defer and async attributes seems to solve the problem.

Many thanks for your help in advance!
