I don't actually see what all the fuss is about...I've looked at the screenshots, and really what are we saying: every control needs to be examined with a magnifying glass and steel rule ??
Just to complicate the matter, do these inconsistencies appear only when the Aero UI is in use? With Vista downgrading it's UI for low-spec hardware would the mis-alignment by the odd pixel or two still be evident?

I suggest there should be a separate section on here for VFP with Vista, rather than this being in Chatter. Surely the bigger issues are going to come with the security lockdown Vista brings to the desktop ?
