I am noticing a problem with the Apple menu top bar. Whenever my iBooks wakes from sleep, it takes a long time, almost a whole minute for the clock to update to the current time. It shows the time when the iBook went to sleep. It used to do this early on but would only take a few seconds for it to update, now it takes almost a minute. During this time, I cannot get the model to dial out, it just stays idle until the clock is updated. Has anybody seen this behavior before? suggestions? Thanks!
