Source editing in popup and not resizable.

[booo9]

For a very long time I used 1.11.x CMSMS,
when editing pages using WSYWIG, there was a check box to switch to HTML code. HTML Editor control for html replaced the wsywig control (embedded in the current page)

I upgraded to 2.x recently, using TinyMCE default editor, when swtiching to html (Pussing "source" button), the source editor windows is a popup. This popup is not resizable. Can source editor control be embedded in the current page and made resizable ?

cheers
