[Samba] Can't save file, disk is full

[Fred Dick]

Samba 2.0.7
Solaris 2.6

When I try and save a file from certain applications (e.g., Photoshop) to a 
samba mapped drive I get the error, "Can't save file, disk is full."

I then save to C:, open Windows Explorer and successfully transfer the file 
to the samba mapped drive.

Any ideas?

Thanks, Fred
