The updated layout of the Admin area is great, but in the update I believe someone was forgotten.
In TinyMCE edit area, the "Link Edit" window pop-up does not work. It is locked, I cannot edit the link, I cannot add a title, etc. Sometimes the only thing that works in it is the "open new window" selection.
In the Source Code window, the same problem. I cannot edit anything in the source code, it is locked. I cannot even copy it to edit it in Notepad++ which provides me a better management of the source code.
Was this intended to be locked? - open these up for use please so the info so we can edit it.
