samba - Feb 2004 - Read-Only file attributes not being preserved.

Hey All,
I'm having problems with samba/windows file attributes.  I'm using
roaming profiles (Win2000) with Samba serving as the PDC. Samba also
stores the profiles. The 'Create Mask'  is 0744 and the 'force
create'
is 00.
Now the problem is my read-only files are not kept at read-only when I
log in. Basically, I create a *read-only* file in my window profiles
directory (say 'My Documents') and logout.  When I log back into
Windows, the file is now *read-write*. The file is also read-write on
the linux machine so Samba has saved it as read-write.
However, turning samba logging to 5, I get the following (The test file
is 'ReadOnlyTest.txt'. My emphasis.):

The file is received by samba as a read-only file but during the 
'renaming' from prf305.tmp to ReadOnlyTest.txt, this info is somehow
lost.
So is anyone else experiencing issues such as this and if solved how.
This is really messing up sourcesafe usage as all the files are
read-write and so no-one code is getting lost!!
