#10 Mailing list administration is buggy?

[Anonymous]

we just installed nu centos 4.7 on a vmware esx server.
everything works fine (including import of about 650 email users and migrating their mails from a cobalt qube2) but the administration of mailings list seems not to work.
it is not possible to add new users to an existing mailing list. if you create for example a mailing list foo with internal user foo1 then after saving it if you reopen the webinterface the user foo isn't marked anymore. so any time you want to add a user, you have to check again all existing users. even worse, cause we have about 650 users and only a 100 are on one page it is completely impossible to edit the list.
is there a bugfix to this issue?
