Description eb1 2012-02-13 08:44:03 UTC
When disposing a Menu its' menu items should also be disposed.

Currently they are not getting disposed when disposing the Menu but will eventually get garbage collected.

I committed this patch without the "menu_items = null;" line. Although this instruction may help the GC, it makes us differ from .NET. It makes it so trying to access a menu item after having disposed the menu throws a NullReferenceException, while .NET throws an ArgumentOutOfRangeException.
