Win7 Aero disabled due to mirror drivers following TightVNC use, cannot re-enable
I'm using a Windows 7 laptop, and a few months ago I installed a VNC server/client program. It seems like a feature of the program changed a driver in a way that turned off Aero. However, I haven't been able to reenable Aero again. I don't want to uninstall this VNC software, I barely even use the VNC server (mainly the client, and the client side part shouldn't change my graphics drivers). When I Googled it and found one of those auto-tech-support type programs from Microsoft for solving problems with enabling Aero, it said something about needing to change my drivers that weren't letting Aero run (I forget the exact words, I can find it again if that would be useful). Also, this computer has run Aero before, with this same edition of Windows 7, so it's not that I don't have Aero in this copy of Windows and it's not that the hardware is incompatible. Any suggestions guys?
