We have migrated a Netware 6.5 SP4 server to new hardware and I used the migration utility to "copy" the files to the new server. The new server is Netware 6.5 SP7. This server is used by Mac OS X 10.5 users.

Today is the first day our Mac users have started using the new server.

One user has reported this error when trying to save Powerpoint files that have been opened from the server:

"xxxxx is currently in use. Powerpoint cannot modify it at this time. Wait until the file becomes available."

Any ideas what is causing this ? I have verified that no other users have this file open.
