ok, this is strange. we have a macbook and a mbox2 pro at church for recording sermons and such. i got the computer, first thing i did was turn screensaver off, and all the energy saver options. this setup has been working flawlessly recording 4 tracks 50min straight for the last 4 months. last week, the macbook started turning the screensaver on while recording. thus causing pt to give an error and stop. in system prefs, the screensaver is set to "never". why would it still be turning on?
