Hi,  This is not meant to slight or make fun of any author in any way
whatsoever, but what I find rather amusing about this thread is this:

Ask a heavy-duty technical question and you might get one reply (if
you're lucky).  Ask a question like "Should I break this seal? " and
it's like the Energizer Bunny -- the thread just keeps going and going.
;-)

Cheers
