[Samba] Cannot rename subfolders in Explorer view

[Nicholas Baldridge]

Samba version : 3.3.2

OS : Ubuntu Jaunty - regular packages from distribution

In the version distributed with Intrepid and earlier, users were able to 
rename subfolders in Explorer view (left-hand pane) in Windows (XP).

Permissions on share are set to 777 temporarily - to no effect.

Share definition follows:
[paperless]
    path = /paperless/file_room/
    read only = No
    create mask = 07775 #Set temporarily
    security mask = 07775 # Set temporarily
    directory mask = 07775 # Set temporarily
    directory security mask = 07775 #Set temporarily
    inherit permissions = Yes
    inherit owner = Yes
    guest ok = Yes #Set temporarily
    delete readonly = Yes

I've been playing around with this on and off since Jaunty release - 
manually reverting back to Intrepid packages with each tested Jaunty 
version. Hopefully someone knows what I'm doing wrong!

I can post whatever information is necessary - just let me know what you 
need.

Thank you in advance,
-Nick
