I have mobileme set up. Occasionally a new event will be created on my mac (set to sync every hour - never sleeping) and I the next day it still will not be synced with my ipod touch (set to sync every 15 min). I never power down the ipod touch (only put it to "sleep"). Other times it will work fine. When I change from "every 15 min" to "push", then the event shows up immediately. Is this common? Am I setting something up wrong? Thanks.
