Hi, following the latest update to iTunes, in the middle of songs, at random times(not the same time for each track - hinting an HD issue) the music sort of 'glitches' for a split second. It is very disturbing when trying to study. any ideas? * following the crappy safari update and its memory leaks, i'm thinking of postponing any updates to my mac for the near future, until Apple gets a better QA team. edit: ok. blamed itunes for no good reason. youtube also jumps the same way. either the iphone headphones start making trouble, or the headphones jack. my apologies iTunes QA team. Safari QA, you're still on my black list.
