I've been having some problems getting Signup for Mac working with Deepfreeze. For some reason, Signup doesn't seem to be able to contact the server during boot, and the deep freeze thawspace seems to start after signup is running. That usually causes signup to report that it cannot find it's configuration. In 8.3, Signup was started by a script so I just added a delay to that. Now in 8.4 that script went away. I wonder if anyone else has had this problem, or has any ideas on how to work around it.
