I am having a gaming system with multiple monitors enabled with Eyefinity. The system was running with Windows 7 Home basic. Everything was working fine since i recently upgraded to Windows 7 Ultimate, i started getting problems with Windows Aero Peek. Now the thumbnail preview and Aero peeks work fine unless i keep Eyefinity disabled. Once i enable it, Windows Aero and thumnail preview stops working. As a troubleshooting i updated my graphic card and all system drivers but yet the same result. What could be the problem and how can i fix it ? Please help.
