hey, i tried posting this in the macbook/macbook pro forum to no avail. basically for the last couple of days my brand new mac has been acting a little strangely, 1. the dock gets stuck in hiding mode, so that when i mouse to the bottom of the screen it does not appear. if i set it to stay put then it works, but it wont come out of hiding OR magnify untill i lof out of my user and log back in, or restart. 2. about 5 days ago i was watching a movie and the sound just cut out...is this normal? 3. i had a system freeze, everything just wouldn't work, but the kernal screen didn't come up, so i waited and waited and eventually hard rebooted. i have been using macintosh for years and have never had these sorts of problems before...should i be thinking about taking my machine back?
