I updated my module to the latest version (6.13), and CKeditor from v3.4.1 to v4.0. Although I cleared caches, did fresh installs, I found that (a) I could not select a new toolbar (eg. Full), (b) CKeditor was stripping a lot of HTML and CSS (changing input filters did not help, and disabling all security filters, made no difference).

In the end, I downgrading the CKeditor from v4.0 to v3.6.6.1 resolved all the issues. Having spent 3 hours on the issue, I was unable to work out where the problem lies.
