[Mailman-Users] Buglet or Bozo? Problems with the /mailman/admin/(listname)/members (ie, membership management admin) page

I've got a problem....I've got a large (600+ user) list

When the list admin (or I, with the site password) go into this page, and try to select a different chunk of users to display on the page, the chunk never changes, it's always the first 30 addresses that are shown.

The URL is changing, but the contents of the page are not.

I dont believe this to be a proxy problem (I dont use one), or cache problem (shift-refresh under IE does not get the correct page)....

Mailman version is 2.0 Python version is 1.6

Does anyone have any ideas?
