We have a General component in Tridion 2013 SP 1 which has a Rich Text Field field called Body.
Opening the component in Chrome (Version 42.0.2311.90 m) and selecting the field Body, the Paste button on the ribbon toolbar is not enabled.
I checked the General schema and checked the "Edit Formatting Features" of the Body field but "Paste" is not included in the list of Formatting Features.
I opened the component in Firefox (37.0.2) and selected the field and the "Paste" button is highlighted. I paste something in the field then the "Paste" button disappears again.
I couldn't open the component in IE11 because it's not been tested there.
As far as I'm aware, this is not a user permission issue. Is there a reason for this? Is there anywhere I can start debugging?
