no, i use sane backend (is the kowa backend for sane?)

1.0.9 on both - client and server

there is another client in the intranet that has not the problems but it 
is an older xsane (0.77 i think) and an older sane version (1.0.7 i 
think), but i'll have a lock again

(xsane 0.77 -> net client 1.0.7 -> saned server 1.0.9 works) (10mbit 
switched)

(xsane 0.90 -> net client 1.0.9 -> saned server 1.0.9 doesn't work) (100mbit switched)
