[MonoDevelop] Normal button GTK# style

[pinggi at centrum.cz]

I'm importing gtkrc style to my GTK# app.
gtkrc style file looks like following:
------------------------------------------------------
gtk_color_scheme = "red:#ff0000"

style "mybuttonstyle"
{
  bg[NORMAL]        = @red
  bg[PRELIGHT]      = @red 
  bg[SELECTED]	    = @red 
  bg[INSENSITIVE]   = @red 
  bg[ACTIVE]        = @red
}

class "GtkButton"    style "mybuttonstyle"
------------------------------------------------------

By this whole button should be red, but it is red only when it is clicked. Like this: http://img846.imageshack.us/img846/9971/formdd.png
It runs on Windows 7 64bit.

Does anybody know why?
