Environment: NW 6.0 with SP4 clustered with NFAP installed.
Mac's have OS X 10.3.5 and 10.3.7 with MS Office 2004 with SP1

Mac's are having a problem whereby - if they open a Word 2004 document and try to save it - it corrupts the file. If they do a save as - it works OK.

The Mac's worked fine with Office 2002.
Novell side of the environment hasn't changed. Mac's have updated to Office 2004.

Any ideas?
