TinyMCE dialog box shows html

Hello Forum,

I have an issue with dialog boxes for tables and links – both of which I think are linked to the TinyMCE plug-in. The link below describes it – the first screenshot is what is should like, the second what it does look like:

I’ve re-set my cache, tested it in different browsers, uninstalled and re-installed and have also tried the only suggested solution I could find over on the TinyMCE forum (which was to hit ctrl+R whilst dialog box open).

Has anyone else encountered and solved a similar problem? Any thoughts gratefully received.

Thanks,

RC
