OpenX: Deactivated Banners to shown in Zone

I have created one Compaign (Ad1_Compaign), and i have put two banners to
that Compaign (Ad1_Compaign). And I have linked these 2 banners(Banner1
and Banner2) to one Zone under one Website.
After that, I am running the Invocation Code for that Zone, it displays
with good (both banners are displaying randomly).
I have two doubts.
Doubt I:
How many times once change the banner everytime page re-loading? How to
measure that?...
Then After I deactivated the Banner1 means, In Zone->Linked Banners shows
good with Inactive Banner.
But generating the Zone Code the Banner1 is also displayed... But it is
deactivated...
Doubt II:
How to block to show Deactivated Banner in Zone?
Anyone Please Help me...
