A customer is using the same version of SQL Developer on the same workstation platform as myself. My Completion Insight works, his does not.
SQL Developer version 3.1.07 on Windows 7 Professional.
Completion Insight is enabled under Tools->Preferences->Completion Insight. Regardless of this setting the ctl + <space> shortcut works instantly for me, but under no circumstances for the customer.
I made a test account on the DB that mirrors customer's privileges - my Completion Insight using the test account still works, so the problem must be with local to his install.
I verified his SQL Developer files came from the same zip file I used for my own installation.
Any ideas what is preventing his Completion from working?
