Select Menu_Bar_02 from the common library and drop into a layer.
Break this instance of the menu bar (select > Modify > Break Apart)
Ungroup the menu bar to show all of its objects
Select the rectangle named "background"
Note that even though the properites panel shows that the rectangle should have a linear gradient fill, when the rectangle is selected no fill handles appear. Moreoever, the object doesn't have a gradient in it, it just appears solid.
Then, if you change the gradient from linear to any other type of gradient, viola! you see the fill handle. And the color changes to what it is suppose to be.
If anyone could shine a light on this I'd be appreciative.
