Ok I know that USB hotsync does not work in 64 bit versions of Vista. Does the same limitation affect tethering to Verizon's VZAccess Manager software? I could care less about syncing (since I do this with another PC) but I frequently use my Treo as a modem with a laptop when traveling (up til now, XP Pro 32 bit). I am being given a new laptop with Vista 64 bit (no option to get 32 bit) but it has not arrived. I have searched these forums without an answer regarding the VZAccess program. IF the USB problem is an ACCESS driver (Palm Desktop), then I might assume that is separate from the Verizon software recognizing the phone as a modem, but I am not sure... Anyone with any experience tethering to Vista 64 bit, input would be appreciated. Thanks!
