Folder Delete Problem - Windows 2003 Server

Has any one experienced problems with Ruby on Rails deleting folders
created with file_column? I have no problems on my local machine, which
is Windows XP. It gets really weird when it tries to delete a folder and
fails. The folder is still on the system, but there are no permissions
assigned to the folder so I can’t open, delete or rename the folder.
When we reboot the server, the folder disappears.

I have tried Stephen S.’ fix to file_column, but because we use sub
folders under the created folder, it does not work. I am hoping someone
has experienced something similar.
