-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 It's a basic principal of UI design that you give the user as many ways of operating a feature as possible and let them choose. Having the mousewheel as one of the mechanisms of control is great as long as it fits the basic metaphor that most people are used for with mousewheels (mousewheels "scroll" in one sense or another). Having it as the only mechanism doesn't just assume that the mousewheel is available (which you are trying to verify here, so that it is no longer a matter of assumption), but that they are physically capable of using it (or using it with ease), and that they want to use it. Which UI people favour is a matter of their physical abilities, personal preferences, how experienced they are, how busy they are etc. Besides which there isn't a way to determine mousewheel availability anyway. Even if you can determine which drivers are on a machine you would get false negatives. -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 6.5.3 for non-commercial use <http://www.pgp.com> iQA/AwUBO+lPsIFpv9f1Mr0YEQIUHQCfbCGR/7apYQNEhg4TpOgUdjKL8yUAoPDa Ceoyejmfukq31Wm4x2QGrca4 =QjdL -----END PGP SIGNATURE-----
