click event in add-in

i'm creating add-in in vb.net for office xp, but my custom button on toolbar doesnt respond to click event
i tried even to use code from:
http://msdn.microsoft.com/library/de...ce06062002.asp
same thing, but if i change .onAction property of a button to run macros it works fine
any idea?
(i set security to low already)
thanks
