yes, that was a flailing attempt to try to bypass the free that apparently
shouldn't be... i'll remove that... or, i think i see what you are saying... if
i use freeandnil instead of the current m1.free, then the nil test might work
and show me that the object is really already gone... i'll try that in addition
to the below...

right... i'm thinking that m1 should contain only the indicated MIME part from
m... ahhh! so what you are saying is that i do not need to explicitly create m1
before assigning m.GetSubPart to it... hummm...
but then i have to wonder why it works the first time and not the second? the
process does show the proper mime parts, one text/plain and the other
text/html... i think i'll manually add a third part to the test message i'm
processing and see if i still get the failure on the second one or if it then
moves to the third one... i'll do this in addition to testing the above

i think the above is one of the main clues... i'll try it out and see what
