Instead, and this is kde-4.5.3, pclos, it claims in the little edge message 
to the left of the message view window, that it is a "no html message", 
when the message structure at the bottom of the message view window does 
show an html component, which if clicked on shows it properly I believe.  I 
would have to call this a bug, but enabling the message structure window 
does enable the viewing of the whole thing once the html is clicked on in 
the message structure window.  But I cannot get enough of it onscreen at 
once to be able to determine if the nesting is proper. Typically one of the 
"offenders" is a megabyte or more.

Lets hope 4.5.4 handles this better. ;-)

Thank you Boyd, for the prompt response.

I have included one of the senders of such in my replies To: list.  From 
this it isn't possible to point a finger at the errant program other than to 
say there seems to be a minor incompatibility between them.

Cheers, Gene
