I have an Intel iMac with OS X 10.5.8. Have been running with Hard Disks and External Disks "Show on Desktop" as unchecked and "Show hidden files and folders" unchecked, and in Windows, renamed the Windows HD Disk" to ".Windows HD Disk". All has worked fine for over a year. All of a sudden, the .Windows HD Disk is on the desktop, as well as the .DS_Store folder. The other hard disks do not display. Despite checking and unchecking the various boxes, and running Onyx, can't make the two icons go away. I'd be most thankful for any help.
