Menu
I've noticed that if you set IsCheckable and have an image for a MenuItem, when the item is checked, the image goes away. Is is possible to get it to work similarly to the old .Net 2.0 so that when it's checked, the image has a border around it? Thanks Paul.

You would need to restyle the MenuItems to achieve that. You can take the default Styles from here, for say Aero, and pull out the Style (and relevant brushes) for the MenuItem. Once you have that, you can customize it all you want.
For MenuItem, you can actually just redefine the SubmenuItemTemplateKey and SubmenuHeaderTemplateKey ControlTemplate, by adding this to your application resources (pulled from file above and tweaked):

You would need to add a reference to PresentationSource.Aero to your project and you may want to darken up the colors for the GlyphPanel when checked.
