After I changed the color of a ToolStrip Control from "control" to a custom
color - anything will do even "controldarkdark", the look of the control is
2D flat.  If you choose Edit->Undo, or manually select backcolor "control"
then  it goes back to 3D office look.    

But, if you change the color like I did and then save the project and close
it --   I can never get it appear to look 3D with the gradient even if I
change the backcolor  to "control" , even though I have VisualStyles = true.  
I even tried ToolStripManager and ToolStripRender.  

This ToolStrip took forever to name each button and event - I don't want to
have to drag and drop again.

Any ideas of what I can do to fix this?
