Problem arises when trying to configure DMZ on Cisco ASA

I have a Cisco ASA5505 that I'm trying to configure a DMZ on.  I have assigned the interface, seethe address, and set the security level.  It seems the next step is to configure static NAT.  I go to the CLI and, under global configuration mode, I create a network object using the object network command.  Once this is done, I should be under the config-network-object configuration mode, but instead I am only under the config-network mode.  The next step is define the subnet, but I cannot do this under this configuration mode.  It should be stated that my box is currently running ASA software version 8.2 (5).  Am I doing something wrong or have I left a step out??  Is this a software bug??  Someone please help point me in the right direction.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The below is an example of the how to use the commands and the prompts taken from the 8.2 software command reference.

hostname(config)# object-group network sjc_eng_ftp_servers
hostname(config-network)# network-object host sjc.eng.ftp.servcers
hostname(config-network)# network-object host
hostname(config-network)# network-object
hostname(config-network)# exit

Can you paste in the command exactly as you are typing them?
