Excel files with macro open only as read-write for the first user that open the file.
If the user close the file and try to re open it then it open as read only.
If another user try to open, also as read only.
If I change the extension to XLS then it opens.
If I copy the file locally it works.
If I copy the file on a Microsoft file system it works.

Novell CLient 2 SP3 and Novell CLient 2 SP3 IR1 & WIndows 7 64 bits

Any idea??
