Jenkins 'Create Item' view (http://localhost:8080/view/all/newJob) requires that the user leaves the field Copy From before the OK button is enabled.

Steps to reproduce:

1. Enter an item name, e.g. 'Hello World'
2. Select an existing job in 'Copy from'
3. [OK Button is still disabled]
4. Press TAB to leave the field 
5. [OK Button is enabled]

Expected user friendly behaviour: after step 2, OK button is enabled
