Can't hide maps :(

[Guest swappa]

Can someone tell me how to hide maps in windows CE for smarphone..

When I try to change the map properties, and mark "Atributes:Hidden" I'm getting an error screen when i press "Done".. "Failed to change attributes"

Can't do it on internal flash memory or on the eksternal card.. :D

Can anyone help me?

Excuse me for my bad english ;)
