	* src/gnome-genius.c: handle read only files properly.  Also verify 
	  text to be proper utf8 before inserting it into the text entry.
	  And the notebook now has a right click menu to switch between
	  programs.

	* src/graphing.c, gtkextra/gtkplotcanvas.c: avoid spurious draws
	  during new plots to avoid flicker when several LinePlot actions
	  are done in sequence.  Also fix gtkextra to honour the freeze 
	  in child draw.
