WPC 7.3 Content editor - article. Why is it 1/3 screen and not full screen?

We are using WPC 7.3 on EP 7.3 SP7 and content editors are compaining that the window to edit content is too small

It is only a 1/3 of the screen and cannot be maximized. They would like to a edit the content in full screen or better yet inline with the layout itself.

Having difficult time getting them to adopt

Any advice on how you deal with this user complaint is appreciated
