I have an interesting quandry. I've been searching like crazy to try and find drivers which will work on Windows 7 64-bit for some of our laptops. The machines are Dell Latitude D620 and D630's which have Core 2 Duo processors (T7200 and T7500 respectively), so 64-bit is the way to go with them.
However, Dell's support site does not offer a driver for Vista 64-bit (which as we know typically works in Windows 7 x64), and the latest drivers from laptopvideo2go.com for Synaptics, which is what I believe these use, doesn't work either.
So, I'm at a crossroads. Have you found a driver that really works well with Windows 7 x64 for this machine's touchpad, or am I barking up the wrong tree?
