Ceridwen:

I'm wondering if certain types of spells stop when the caster is dead 
(it would be very inconvenient for someone to remain frozen for the 
rest of their lives if the caster dies, as Harry was frozen)?  Or, if 
perhaps certain things are done to make a charm or spell last longer 
than the life of the caster?  Or, if charms and wards last while spells 
have a natural lifespan?  None of the answers to these things have been 
clear to me just reading through the books.
