Just got CCC working, but now I've got no display manager in this version! Where will be the best place to procure said 9.5 driver and when is it supposed to be available?

Makes sense....looks like ATI kinda dropped the ball on this one. Will await this 9.5 with 'bated breath. Thanks for the information.

win7 wont detect 2nd monitor

Windows 7 upgrade won't detect 2nd monitor
I recently upgraded a system with Windows Vista to Windows 7 Enterprise. I had problems when it would not detect the second monitor. I tried everything downloading different drivers from different websites. I finally found the solution on my own. 1st download the driver you know is the correct or best for your system and save it on your desktop do not install it. Next open device manager and and uninstall display adapters, and restart your computer. By now you have propbly downloaded so many drivers that you are confusing the instructions to turn on your second monitor. Check to see if you can extend the second monitor by pressing the Windows + P key at the same time. Try to extend the monitor. If it doesnt pick up keep uninstalling and tring same steps over. Finally when no more drivers are left your system should take the one driver. The Intel(R) Q45/ Q43 worked for me. So good luck this finally worked for me. The key is to keep uninstalling and restarting to see if your system keeps tring to install new found hardware on its own.

Does windows recognize the drivers for your mobile GPU?

I actually found out why this was happening. I was plugging my second monitor into the wrong port. I have two VGA ports and only one of them is the active graphics card.
