I've come to the conclusion that there is some kind of caching going on
with gnus, and that if I close my gnus down when I hit some problems,
and then not open or use it in any form for over 5 hours, the cache
forgets and the problem is solved! The figure of 5 hours is purely
arbitrary, just plucked out of thin air!

Am I right?

Sharon.
