#1 SetVerbState fuction not work correctly

[Anonymous]

Windows 2000 pro
.NET FrameWork 1.1
MMC 1.5
MMCLib 1.0
---------------------------------------------------

We created a snap-in like 'ADUC' with MMCLib and had
our own users/groups. We set the 'Delete' verb to every
user/group item with the SetVerbState() fuction. It
worked well when we select only one user/group, but if
we select more than one, the 'Delete' verb wouldn't
work.It would work when we test in other os above win2k
(eg: winxp, win2003).

We tested ADUC(win2k) and found no matter single-
select or muti-select, the 'Delete' verb worked well.
