Steps to reproduce:

1) Create a Load test
2) Start capturing a new User Profile
3) Capture a profile that navigates to Wikipedia.org
4) Open the "Edit User profile" menu
5) Go to step GET http://www.wikipedia.org
6) Go to Reponse section
7) Scroll down and click the Decode Now button
Expected: the gzip encoding which Wikipedia utilizes is decoded to make it plain, human-readable HTML code. You can easily do this in Fiddler and review the HTML code that the wiki server returned to your browser
Actually: In Test Studio the Decode Now button doesn't seem to do anything. The Content field remains empty.
