CLASS: CAddressBand
DESCRIPTION:
This Class CAddressBand exists to support a "Address" Band
ToolBar. This will be used in the Browser's toolbar or can
be used in the Start Menu/Taskbar. If the Band is part of
a Browser toolbar, any modifications made to the AddressBar
will go the the browser window.
By default, the this AddressBand will not point to a
browser window when it is on the Taskbar or Start Menu.
Anything "executed" in the AddressBar will create a new
browser window. Future support may allow for the AddressBand
in the taskbar/start menu to reference a currently existing
browser window.
