Ok.  Then I really don't understand what is hapenning.  Below is an example:
user rneuman on pc01718 (WinY2k, M$-Office) can't open 1893.doc because it says
it is already in use by user rneuman.  This seems to start out gradually and
grow to a calamitous situation,  restarting Samba helps for awhile and then it
comes creeping back.
