iCal on book isn't matching cloud... how do I resync?  don't want to hit the wrong thing!!

___________

To be sure the calendars are syncing, and I checked several times, you should go to your mobileme system preferences in system preferences and select the sync tab within mobileme.  Next, be sure that automatic is selected and not manual or every hour etc...There you'll also find the sync button.  Select that and you should see the icon in the menu bar begin to spin.  You can also force sync from the drop down under the circular arrow icon in the menu bar as well.
