[Samba] Unable to delete files in shares

[MList]

Samba users,

i have a samba server running samba 2.2.8a, and some mandrake linux clients.
i find i am unable to delete subfolders in shares that i have created. the 
subfolders are empty. for subfolders that have files,  i can delete files 
inside them.

second problem, i find that if i add option read only=yes for a particular 
share, testparm shows it to be read only=no. why does this happen

i am using smb4k for network browsing.
