Using Windows Sharepoint Services Webdav with Mac OSX

I am trying to set up a intranet based on WSS.
I would like to access wss document libraries via webdav. I can with Windows
XP, and I also can read files from Mac OSX. I also need to write files from
Mac OSX, but that does not work. It creates the file but empty!
As I can write files to other Webdav folders from Mac OSX, I believe this is
a issue on WSS.
Is this a feature or a bug? Will it change in the future?

Best regards,

Its funny that I can't find any posts anywhere for this problem. The error messages mac os are giving are ridiculously simplistic.

"The operation cannot be completed because the item is in use"

or

"the operation cannot be completed because there is a missing item".

Ok...

I don't know what the deal is. Is it a macos problem or a windows problem, where to go from here. I really would like to get this resolved we have a client depending on this functionality.
