I've noticed a very strange peculiarity: In Windows XP Home Ed SP1, fully up to date with patces, and with all hard disk partitions formatted as NTFS: Right-click on any folder on a hard disk and select the Properties option. Take a look at the Read-Only attribute. It's a green square. All attempts at changing it fail. Next time you look, the green square's back. I wasted a few days trying to understand this. Then I posted the question on a few other forums (Scott Finnie, Lockergnome). The general consensusm there was that it is bizarre, but normal behaviour. It doesn't affect the files in the folder at all, nor does it stop you renaming, moving or deleting the folder. Can anyone explain what is happening a bit more? John
