NX 8.5, Space Pilot Pro and the Print Screen Key

[Matthew2323]

I'm trying to set one of my Space Pilot Pro keys to utilize the "Print Screen" button. Since the function does not exist in the list provided (that I can find) I tried to create a custom function. When I select "New" under Custom Functions in the Space Pilot menu and select the "Print Sreen" key it does not appear in the dialog box. (Other keys do appear when typed.)

Has anyone else tried to add this key and been successful?

I'm running NX 8.5 on a Dell laptop with Windows 7 (64-bit).

Thanks,
Matthew
