Ok, this is sorta hard to explain, but I'll do my best:

An Appbar - Like the taskbar, they stop any other apps going in front of them. They make all the windows smaller so that they take always take up space on your screen (eg AllAdvantage)

Is there any way to stop an application from being an appbar?
(Guess what its for! (read to make other apps go over alladvantage)

Anyway, any help would be appreciated
