Sorry, I usually do, and in fact with this particular reply, I originally 
nuked all the quotes and then thought better of it....That's what I get 
for using the e-mail interface rather than the gmane interface. ;-)

Thanks for this great explanation of the differences between old and new 
pan - that really helps.

Not turned on - I have it set to pull new headers at startup, otherwise 
just when I hit Shift+A (still getting used to that instead of CTRL+SHIFT
+U).

OK, that explains why with a large number of headers there was a bit of a 
slowdown upon entering the group.  Now that I've pruned back the headers 
(one group in particular has about 650,000 messages in it and was clearly 
showing the issue)

I use pan primarily for reading text-only newsgroups, so decode-and-save 
isn't an issue for me.
