What steps will reproduce the problem?

2. recaptcha fails to display at register and contactus pages in IE11.
3. Browse back and forth register and contact us page at the login screen 
without a hard refresh in IE11.

What is the expected output? What do you see instead?
captcha verification should be displayed at all times in these pages as it does 
in Opera, Firefox, Safari and Chrome.

What version of the product are you using? On what operating system?
recaptcha 1.0.3(2015-03-24)

Please provide any additional information below.

IE11 does not displays the captcha challenge at register and contactus forms 
after browsing between these pages, unless the page is hard refreshed. As 
consequence users can register and make use of the contact form without a 
captcha challenge.
