I have a Dell Latitude E6446 running 64 bit, and after upgrading from Windows 7 to Windows 8.1, my two finger scroll stopped working. I know there are many other posts like this, but none of their solutions seemed to help me. My mouse driver is Cirque GlidePoint, I believe, and even after downloading the latest driver, a dialogue box comes up saying, "There are no active devices available to configure. Path: Software\Cirque\GlidePoint Touchpad\3.7"
Any help will be greatly appreciated!
