PDK menu not showing in CIW

Hello:

After updating to IC6.1.7-64b.500.12. I am having an issue where the PDK menu is not showing up in the command Interpreter Window. I didn’t have any problem with the previous version of IC6.1.7-64b.500.10.

Instead of the PDK menu showing in the CIW like this:

The menu disappears from the CIW like this: 

The PDK menu must show in the CIW. That is the only way I am able to create a new library. 

Thank you so much
