I think my brand new powerbook is a lemon. When I first got the powerbook, I noticed an issue that popped up whenever it went to sleep. Upon waking up, whenever I would begin to type, the letters would be Greek letters and I would have to restart to get it to type normally. Now that I'm uploading my music & photos I'm noticing other problems. After ripping about 5 CDs to iTunes, my computer would refuse to resolve web pages. When I went into Finder>Netork I would see that it was still connected. Also, at one point, it couldn't find my iTunes library! I freaked! But after I restarted the computer my iTunes library was once again accessible. My iMovie also crashed after I tried to make a movie! I'm very upset cuz I've been drooling over this machine since last September & have been dying to switch from my dinosaur of a PC. I've been lurking on various Mac forums & have never seen anyone with these kinds of issues. Since I got the machine, I've always repaired permissions after downloading a new update or program. I don't know what I'm doing wrong. Can anyone provide any insight or should I just go back to Compusa & exchange it? Please help!
