XP share - permission denied only after downloading - please help!

[greg]

I just upgraded Samba to 2.2.2 and it's still happening. I have a 
Windows XP Pro machine as my desktop and a Linux machine as my 
gateway/firewall. The XP machine (which is connected directly to 
the gateway thru cat5) has a few shared directories which I can 
successfully mount on my Linux machine. However, when I download a 
file on a XP shared dir and try to move/copy the file from the 
samba mount on linux to /var/tmp, I get "Permission denied".

OK now here's the fun part! I move the downloaded file from the 
shared dir to another dir then move it back to the shared 
dir..only then can i move/copy the file from the linux samba mount!

Can this be circumvented by tweaking the smb.conf file, or is it 
totally XP's fault and I have to figure out how to set initial 
perms on downloaded files?
