Actual version of CKEditor I was using is 4.0.1.1. I reverted back to CKEditor 4.0 and it worked in IE7 as well. It seems there is some problem with version 4.0.1.1.

I had a similar problem with IE9 downgraded to emulate IE7. Then I did not get a context menu.
By forcing the document mode to at least IE8 it worked as expected.

I was having this same issue in a Symfony2 project.
Oddly I noticed that the dropdowns worked in the Symfony2 development environment, and discovered that they worked when the Sf2 debug bar was enabled.
I then did some inspection in chrome and found the CKEditor dropdown elements are in an iframe that's added as the last element in the body.
I then tried adding an empty div tag as the last element in the body (previously the last element was a script tag), and that fixed the problem.
So, add a plain, empty div tag as the last element of the body and the dropdowns are all ok.
