Review Details button not launching from Planning Overview

Hi there,

I have run into a strange problem revolving around the launching of the Review Details iView from Planning Overview. We are testing using a test user id. I log in on my machine, go to the Planning Overview iView, select a user and click the Review Details button. The iView launches for me. When I log into the portal on another users machine, still using the same test user id, follow the same steps, the Review Details does not launch.

I've gone through the Tools -> Internet Options within Internet Explorer (we are using IE9) on both machines and didn't find anything that stood out as a major difference.

Anyone ran into this problem, or have an idea of what the problem might be?

Thanks!

Kevin
