What's the oldest app you have running on ANY version of Vista?
Mine has to be GraphicType Designer. Been using it since Windows 3.1!!!
Works well under Vista Business 32bit but will not run on ista 64bit.
P.S. GraphicType designer is an app which allows you to create borders and surface pattern designs for use in DTP, graphics, illustration, image editing and word processing applications.
