I started using Pure Calendar today and love it. But I have one question. There is a "Select Update Frequency" setting that can change from 6 hours to "When Calendar is Modified." I left mine on 6 hours to begin with, but I have noticed that when I modify my Exchange or my Google Calendar (on my phone OR on my computer), the Pure Calendar widget updates almost instantly. Anybody know why? Is it a bug in the Widget? Or is it supposed to update the Widget instantly despite being set to 6 hours?
