I'd like to try a summery from what I've learned so far here, (Besides some massive reading and experimentation...) 1. Get a new external disc, reinstall the Logic version you once were happy with and keep on listening to your old songs you've already finished, that's why you put them there. 2. Write new songs right now, you've proven in the past. 3. Get more RAM, that's a conclusion here, I have the same computer as your's, running 1 G of ram, no complaints. 4. If you feel you're having problems, have the machine running at 3 AM, that's the time Apple's own maintainance programs start to work, Onyx is nixe and free, but not working in Tiger right now, as I have posted before, probably there are negotiations goin' on... my observation is, my apple's has been refreshed without deleting anything you might need later... If this gives you some confidence, make a habit out of running repairing permissions before going to bed... 5. Do not delete anything, get organized in a 4 folder way, you might make some money with that later... 6. Forget about crashes, they are past since OS X.4, but don't start unless OS X.4.6
