Just changed from using setDefaultLookAndFeel() in a plugin to relying on LookAndFeel inheritance and I've found a problem.
If you set the look and feel for a parent component then add a Slider the slider fails to notice that the parent has a look and feel assigned and doesn't update its text box.
This means you get a different behaviour depending on when you set the parents look and feel. Which is odd behaviour!
I think that the addChildComponent should check for a new look and feel and then send the right change notifications .. but I don't think that happens?
... anyway, a few more weird things left to sort out now - better get back to it:)
