Thanks for the further suggestion Bob. Unfortunately the problem persists in Private Mode. Very Curious...
Cheers - Mark
I ran into this problem myself a year or so ago and I believe if memory serves it was because I swapped over to a different rich text editor. To date I believe there are two variations of TinyMCE and also there is TinyMCEWrapper. I'd suggest trying a different TinyMCE editor to what you have been using and this may solve your issue?
Had the exact same problem on a 2.2.16 site yesterday, I removed the TinyMCE editor and installed CKEditor which works.
Didn't really have time to look into it too much but did try both TinyMNC addons and both caused the same issues.

I'm pretty sure that was actually the issue for me too. Not the confliction of the two TinyMCE's but rather swapping to and from CKEditor.
