The likely cause of the problem is Desktop file got corrupted when you did a Desktop rebuild with SuperATM (other extensions can cause it too) loaded.
The problem with the Desktop can be verified with Norton Utilities or MacTools but, they can only offer a temporary fix. The problem may go away for a while, but could reoccur.
The long term solution is to rebuild the desktop with the extensions off thus eliminating the possibility of any extension interfering with the rebuilding of the Desktop file.
Occasionally the situation you are experiencing could be related to a formatting corruption. So, in addition to rebuilding the desktop, you may also want to update the SCSI driver using Apple HDSC Setup while booted from your Disk Tools floppy disk. For more information about updating SCSI drivers see "Apple HD SC Setup: Updating SCSI Disk Drivers (1/95)."
If you have reformatted your hard drive with a third party utlity, you will need to follow the driver update instructions that came with that utility.
