Just now I had the same problem, a msg box appeared with
"invalid operation, program terminated", my Mozilla 1.0 under XP has
been closed and I lost virtually everything. I gave a look into the
files under the user-root directory and my sensation is that Mozilla
encodes somewhere user profile data in the folder name placed under
the user folder name (mine is 9sdr-and-so-on) . I tried several
solutions, renamed files, folders creating user profiles
before/after the various operations attempted but I got nothing. I
am afraid that some others have the same problem that could - a
personal opinion - easily fixed by the developers if the allowed a
mozilla profile among the import options. If I have examined well,
such options seems not to exist. Now I am in great troubles because
Moz crashed 3 times in the last week and it is a very good mailer
I'd be sorry to migrate away from. In case nobody knows how to fix
the problem avoiding re-setting up accounts and so on, I think that
we could ask the developers newsgroups, I can guess that we will be
excused for the (near) OT. Maybe some hand-editing of certain files
may help solving this kind of problems.
Some ideas??? I'd like to avoid resetting up everything for the
4th time :((((
