I followed the same procedures to fix the wireless, but it did not work. I had to download the Atheros drivers from Softpedia. Actually it is a IBM Thinkpad install that you need to pull the drivers from the WINXP_2K folder.
Also, the right-click and scroll issues are back and I have yet to figure out how to fix. When I try to manually install the Apple drivers, Vista keeps telling me the Best Drivers are already installed. It won't allow me to change/update them - thanks for nothing. If I ever figure it out, I will post here.
