Hi Jake -

   thanks for the update on this, that behavior was really driving me 
crazy as it made
no sense based on what you were doing. Can you briefly summarize what 
the bug is
so that when someone else sees the same thing, we may have some 
collective memory
of a possible source?

   thanks -- Curtis
