I've found nested Applications folders on my new iMac running 10.6.8. There are three levels: Applications>Applications>Applications. NONE of these are aliases! The most deeply nested folder went to Trash (with all its contents), and emptied from Trash. The middle folder (one level down from the main Apps folder) will go to trash but will not empty from trash - neither will any of the items in it, not even one at a time. I get "The operation cant be completed because an unexpected error occurred (error code -8003)." I've repaired permissions and verified the startup disk. Help please.
