Ah! No, sorry.

I can drag it around no problem. As for resizing, it doesn't work. The 
cursor shows the appropriate shapes when near the window borders, but 
dragging it by the border can only move it (i.e. dragging the top or 
left border moves the child frame, but does not resize it).

Dragging it by the border is not as snappy as dragging it by the 
mode-line, BTW.
