EDIT: You can bow create your own "Recent Comments" widgets using the Recent Comments widget generator here at Blogger Buster.
Since the Recent Comments Widget suddenly stopped working in IE7, I've updated the code and uploaded it to my site in order for us all to continue using it! You can download the new code below. I've tested this in both IE and Firefox and it seems to work just fine (take a look in my right sidebar).
If anyone has problems using this widget, please let me know!
