I can confirm this behavior on Thunderbird 3.1.9, Lightning 1.0b3pre, Exchange Provider 0.12.
I have three calendars: Google, Exchange and Local ( moz-storage-calendar:// )
All my tasks are in the local calendar.
Starting Thunderbird with the Exchange calendar visible causes my previously saved local tasks not to display. I can still create local tasks in this state. These tasks are visible during the session, behave normally and persist after quitting.
I'm able and willing to provide more info and/or try patches.
