Minor bug I thought I'd report:

If I set: USE_SECURE_ADMIN => 1;
and click 'Manage', Firefox displays an error:

(my site) has sent an incorrect or unexpected message. Error code: -12263

The perl test script floating around this board works fine for me, and so does my imageboard when that option is not enabled, so it should be a genuine bug.

Running Firefox 2.0.0.3, Perl 5.8.7
