NotebookWrite is a relatively low level function, it has been there even 
before version 6, which means before all the dynamic stuff to create 
graphical user interface. Thus it expects either a string or boxes for 
2d content. It is fortunately almost trivial to create these boxes, so 
this should work (and it will work with everything: Graphics, 
Graphics3D, Manipulate ...):

NotebookWrite[nbControl,ToBoxes[mItem], All]

in fact I've never seen Paste, presumably because I knew ToBoxes and 
never had the need for it. Paste basically seems to be the high level 
version of NotebookWrite. Good to know, it will make some code more 
compact and clean. It would be interesting to know whether it really is 
equivalent to NotebookWrite[#1,ToBoxes[#2]]& ...

cheers,
