Thanks Ned!  I'm glad to know that this wasn't my fault (for once).  Now how
'bout it Apple?!?  Ned says he submitted this bug over a year ago, but it
still happens in 6.0.3!  I've got 5 meg of memory in my machine, so I
can afford to lose 8K now and then, but what about the rest of the world
(and the Mac I use at work)??  It seems like a small enough problem that
the fix can't be that bad.
