Ckeditor incompatible with gravity forms

Hi, with ckeditor several features of gravity forms stop working. Gravity forms is a major plugin, would be cool if you could check with them how to get it fixed.
Errors I found:
– on pages and post edit screens the button to add a form isn’t working.
– on notifications merge tags can’t be added to the message fields.
In both cases the options are offered, but the plugin seems to be unable to add content to the field.
