Mine have always looked like that - I think!  What's the problem?  I 
have noticed that there's nothing to explicitly collapse or expand all 
threads, and it's a real shame that you can't delete an entire thread 
easily.  The work-around for the first problem seems to be to move to 
another mailbox and then back, whereupon all the threads are collapsed.
