Posting comments using WordPress and IE

After my article yesterday reg the problems with writing a post using IE8 (http://manaadiar.wordpress.com/2008/12/18/ie8-affecting-wordpress-performance/), also notice that when there is a comment and you try to respond to it using the reply mode in the comment (after you approve it), IE8 is just showing a blinking text cursor in the reply box, but when you type it, it doesnt do anything.. all other browsers are working fine.. 

Anyone know a workaround for this..??
