Regsitering using IE9 fails

I tried to register with the site using IE9. It failed every time because I did not see the Captcha block on the registration page. I switched to FF14 and saw what I had missed and completed the registration.
Is this a subtle way to prevent MS users accessing your site?

I would say it´s a subtle way from MS to prevent you from viewing the web like it could and should be viewed… Microsoft does a lot of good software, IE is not one of them unfortunately…
