Your 7290 and computer may not have any Bluetooth profiles in common.
Turn on your 7290's Bluetooth, click the Options icon, choose the Bluetooth entry, click to bring up the menu, and click the Options entry. You should see the 7290's Bluetooth profiles listed under Services. Those are the only profiles your 7290 supports. Your computer will have a different set of supported profiles. If two communicating Bluetooth devices don't have a profile in common, they may be able to pair up, but they won't be able to do anything together.
If you've been able to pair your computer with your 7290, click the Options/Bluetooth entry for your computer, and select Device Properties. You should see your computer's supported profiles listed under Services. Compare those services with the services for your 7290 to see if there's a match.
