my friend's having a problem with OS 9. since i'm far less familiar with OS 9 than OS X, i was wondering if someone here can help me out. she adjusts her Mac's volume level using the control panel, but the Mac has problems remembering it. every time she re-starts her Mac, the sound volume reverts back to the pre-setting level. is there an equivalent to preferences file in OS 9? could she trash that to possibly fix this problem? any help is appreciated.
