Try mapping with SMB. go connect to server

Paul,
For Mac users, connecting to the server via SMB protocol is not an option. Files (particularly fonts and Quark XPress files) get corrupted when copying files using Samba.
The option to connect using the Apple protocol seems to have worked in previous versions of Mac OS X. I'm assuming Apple did something to the Apple protocol (perhaps made it more secure?) when they released Leopard.
Any plans to release an update to your network storage products to resolve this issue? I bought a Buffalo network file server SPECIFICALLY because it supported Apple, but now it doesnt.
