Sun OS machine using contribute version CS3 when ever the users publish their
changes or create new pages the changes are uploaded but the permissions for
the file are reset to 600 (rw- --- ---) meaning that the page cannot be viewed
in the browser anymore, and more importantly is not visible in contribute, the
only way I have found of fixing this is to ftp into the site and set the
permissions to 644, this is not a realistic solution when we give contribute
out to more users.

Is there an admin setting that can be changed to change the default permission
to 644?
