There is a nasty bug in the product, which is fixed in the latest version 1.0.4 which have have just released.
If you are running the previous version, please update to V 1.0.4.
The bug affects users who run the batch CO:Z launcher with certain configurations AND under a userid with certain SAF/RACF SUPERUSER privileges.
Even though we have fixed the bug, as a general policy we don't recommend running under UID(0) or SUPERUSER privileges.
