Because the underlying toolkit uses its own "picture" object that is not 
automatically reassigned to the control automatically. In other words, assume 
that the Picture property returns a copy of the underlying picture.

I did a workaround only for the Control.Font property. I mean, settings 
Control.Font.Bold for example automatically reassigns the control font so that 
you see the change.

So, yes!
