[Samba] caching problem

[remco]

i have just installed samba on my gentoo server. but im having a 
problem: some applications wich run find from a winXP 'fileserver' fails 
  when working from samba. everything seems to be fine but (its a 
compiler for a microcontroller) the produces file is not updated. its 
just re-recrated when i delete it.

i think its a caching problem somewhere.

can someone help me with this?

thanks,
remco
