We've been having this problem at Stevenson College Edinburgh for the longest time, and I thought I'd try asking (again?) here to see if anyone knows anything about it. We are running Logic Pro.latest on iMacs running Tiger 10.4.11. We have set it up so that the students have individual logons (pulled in through Active Directory, I think), which then automatically connect them to a network home where they are supposed to save their files. The machines are set up so that the local home on the machine they are at gets wiped each time they log on, we wanted to enforce people saving files to the server rather than local machines. The files are being saved to some sort of Windows NAS box, although we also have an Xserve in the equation somewhere; getting vague here, I'm not really the networking guy... So, the problem is that when you try to save a file to the server, Logic says 'sorry, can't do that' or some such message. However, in fact it *does* save the file to the server. If you then resave the file, again you get an error message; this time it resaves the file appending a tilde to the name foobar~.logic. As time goes on students end up with a confusing mess of files called things like foobar~~~~~~.logic. Does anyone know what might be going on here?
