My company runs peachtree 2006 accounting software in network (multi-user) mode, with data files stored on a samba server. It works as well with Linux as it does with Windows. There are some lockup problems due to the Windows clients not releasing files after an app closes, but at least with samba you can close lingering connections from clients. This may not be an option for some due to corporate policy. However if you can change over, you will find fewer bugs and better support to boot. Cheers
