Unfortunately, I don't know any of the above or I would definitely have
fixed it by now.  It's intermittent, though at least after two years I've
found a way to reproduce it fairly reliably with an adequate number of 
clicks between a particular set of links I use often.  The cookies that
are lost are both session and persistent: in fact all cookies pertaining
to one particular domain are lost simultaneously, it seems.  My own
browser (IE).  Using a home-brew issue tracker that was written largely
with DTML about three years ago...  at the moment I'm still assuming
it's a problem only with that product, but it does not affect Mozilla
at all so it's clearly linked to IE-specific behaviour.

Hmm.... I doubt they're supposed to vanish if there is not too much
data stored in them, and as there are no reports that I can find on the
web about similar behaviour, I suspect they _don't_ vanish, even if they're
allowed to.
