BuddyPress.org

hello,
i am running buddypress 1.2.3 (also the latest) and wp 2.9.2 , and there also problems with the multiselectbox.
It ist not possible for users to save the content of the list in the profile, but it is possible to select more then one item in the list.

the result is: it does not , what it should do ? — the multiselectbox is not usable for websites.
