think you're saying you have Classic launch on Startup.
If you don't want it to launch until you need it.
Uncheck that option in System Preferences > Classic.
It is not surprising that some Hardware will work under OS 9,
but not work running under Classic in OS X.
You can probably just keep doing what you're doing.
Buy a new Burner or buy a newer version of Toast.
Trish. Which Burner?
