I've seen two instances where this can happen.
1. The user creates the file in a directory with full perms, but the file
   is created r-x, which means the user can not then modify it afterward.
2. Certain systems (Netatalk is the one that comes to mind) create the
   file and then change the user.group.  If permissions are set just wrong,
   the program will be unable to change the user.group and the file ends
   up with permissions that the user never expected.

More research into exactly what is happening will probably help uncover
what the problem is.  For example, after the problem occurrs, who is
the actual owner of the file, and what are the permissions.  What is this
compared to what you expect?  Quite possible, there's some sort of user
mapping going on between Win/Samba which is causing the problem.
