I am having trouble saving my gnucash file to my samba network share. When ever I try to save it, it says "The File /mnt/joseph/gnucash/2000 appears to be in use by another user. If this is not right, remove the .LCK file and try again." How do I save to my network share. I have tried to find the .LCK file and can't locate it. Any help would be appreciated. Thanks.
