[Samba] cant save to smb from apps?

[Josh Hester]

I set up a samba share on a fedora core 5 box.

I am able to drag and drop files to it, but when I try to save from an 
app, I get a message saying disk is full.  These are all XP home clients. 
When I tried to share from an XP pro client it worked.

Any ideas on how to fix this?

thanks, Josh.
