A long, long time ago (last year sometime), I started work on an article about dealing with Internet Explorer's limitations when it came to buttons and image inputs in HTML documents.
I was reminded about it a couple of weeks ago, when Drew wrote his article Coping With Internet Explorer's Mishandling of Buttons. This isn't a case of "Drat, now all my work is wasted" though, since I've been taking a different approach.
So, now I've finished editing it, you can read Multiple HTML submit buttons a shortcoming of Microsoft Internet Explorer and what you can do about it over at The Developers Archive.
