[TxMt] Error saving across AFP - "atomic save: invalid argument"

[Alastair]

Hi.

At work we have AFP-mounted shared folders.

I can open files in TM2 on these no problem, but when attempting to save I get:

The document "XXXX" could not be saved.
Atomic save: Invalid argument

No console messages that I can see.

I'm using Version 2.0 (9090) on OS 10.7.4

Any ideas?

Thanks very much,
Alastair.
