Middle button
Same problem here. Can't pan in Autocad or Ecotect. Latter app makes virtualization a 'no option'. Was hoping there would be a two finger click, but it's looking like a Logitech mouse for Bootcamp. May I add that scrolling with MM on W7 is not smooth at all; except in Autodesk apps where it's just fine - makes it all the more annoying!
Been lookIn for third party drivers online, but nada. Let's try to keep this thread alive.
