Hi Bruce, Open the Aero troubleshooter by clicking the Start button, and then clicking Control Panel. In the search box, type Troubleshooter, click Troubleshooting, and then, under Appearance and Personalization, click Display Aero desktop effects. Administrator permission required If you're prompted for an administrator password or confirmation, type the password or provide confirmation to continue to troubleshoot, restart Windows once done and check the issue still persisting.
