[X4U] Finder locks up-help

[Robert A. (Bob) Hall]

I have strange condition that I have not seen before. I now cannot 
open my Documents folder by clicking on the Document Icon (folder 
title "Documents"), while I can get to the files in the folder by 
clicking the arrow in front of "Documents" in my home folder. When I 
click on the folder title "Documents" I get a spinning wheel and the 
finder locks up. Force Quitting restarts the Finder restoring all 
operations except opening the Documents folder.

All other folders open as expected. No other action I have tried 
locks the finder.

I have rebuilt using  DiskWarrior, reset parameters, restored disk 
permissions, repaired the disk using Disk Utility (after restarting 
to my backup hard disk) -- to no avail. As an an experiment I moved 
the moved the Documents folder to a backup hard disk and it work 
perfectly. Moved the now operational folder back into my main disk 
and it still locks the finder.

This all started when I tried to drop a file from the my "download" 
folder into "Documents" in the side bar. It opened a blank window and 
the cursor changed to a spinning wheel.

Any comment will be appreciated.
