I have a Quicksilver G4, and I did something that resulted in everything on my desktop increasing in size to about 1 1/2 times the usual size and I cannot figure out how to restore it to the ususal size. Help! Also, when I copy a music CD on my powerbook G4 and burn it, it will play just fine on Mac computers, but not on others and not in the CD player in my car. I do not know how to correct this, but it seems like I am not burning it the right way, or something similar. Bill
