After the latest Internet Worm Turned onto my system, I did a total reformat and reinstallation of Windows XP Home. I was really hoping that this would allow me to use the CAT 3.6 Drivers and not have any problems when I reboot with the Video OUT connected.
No go.
The latest version that does work for me is still the CAT 3.4s. They work just fine in enough areas that I'll stick with these until the newer CATs come out.
