The drive this is happening on is partitioned in half - one has a Journaled Volume for my Panther dual-boot, and the other half is storage, NTFS format. Ive noticed that some of the folders are hidden, and there is now an application with the same name - if I open the hidden folder or the application, I can see and access all my files, but a) why is this happening/what caused it and b) how do I put it back to normal/prevent it from happening again?
