i believe there is both a in memory cache and an in schematic file cache
closing and reopening the file does not clear the memory cache as i
recall
you have to close the whole protel session
i think this was cleaned up somewhere along the way so that i have not
found it to be much of a problem
please correct me if i am wrong about this behavoir
