Jim; Try Repairing Permisions with Disk First Aid (or whatever they call it now).

Maybe if you have a partition you could try this on before messing with what you already have it would be a viable option. jj On Tuesday, June 10, 2003, at 12:51 PM, Power Macintosh G4 List wrote: > > ORIGINAL From: Jim Robertson <jamesrob at sonic.net> > > Subsequent to doing the 10.2.6 update, my computer misbehaves in two > areas. > > First, it won't sleep. > Second, my Epson Perfection 1200U scanner no longer works. > > People at the Genius Bar suggested I try making a new user— same > insomnia. > > I tried unplugging my USB hub.
