did you get the region onto the 2nd display? you select the display on the right hand side.

a few other things to check:

1. make sure keyclone/setup/maximizer/enable-maximizer is CHECKED
2. make sure the name of the region under maximizer matches EXACTLY the name on the command
3. make sure there are no other commands using the same region name
4. make sure the region name is unique across the regions
5. make sure there are no spaces or case difference between the region name and the name you specified on the command panel

let me know if you're still messed up.
