Garageband, repairing permissions? Options

[Barb]

I am using GarageBand for my introductory classes on the high school level. Logic Pro for my advanced classes. All this is new since we upgraded to 10.3.5 and 512 mgs of RAM. GarageBand often can't hold more than 6 tracks of MIDI for more than 30 or so measures before it cuts out. Also, it freezes when quiting.

I read someone make a comment about "repairing permissions". Does anyone know anything about this?

Thanks!

I must admit that I am also having some problems with Garageband (and other applications). I recently installed some extra RAM hoping this would solve some of the issues, but whilst it has had an effect on other programs, there does not seem to be any benefit within garageband (quite the opposite, in fact!).

A while back I installed OSX 10.3.5 and find it quite stable, so I am not sure that this is a factor either.

Since I often repair permissions, and run the maintenance scripts, I am a little bit at a loss to understand what is going on.

Interestingly, my Pro Tools LE is also slower these days.

Other than a more serious issue going on under the bonnet, I imagine that there must be some problem with the Core Audio drivers???
