in same boat as jackal...
actually - If I look at any folder in ah2, ie skins, cache, filmes, ect.....properties show a green box highlighting readonly.
edit - all files on my system have the green box highlighting read-only. There is no check there. Clicking it will make it go away, but will come right back.
also Pyro - no disk compression or management software.
Using NTFS setup.
Files in the folder have no black check boxes in their properties.
Maybe just an XP oddity - which means a false alarm
