Windows, Amiga, BeOS, Gnome, Mac, CDE, FluxBox, ICEWM, and any other graphical interface that I ever used are all using the "click to select, double-click to operate" paradigm. Speaking of UI research, some people might be interested in the KDE Usability Project: http://usability.kde.org/activity/testing/firststeps/index2.php It's from last summer. Test participants were between 20 and 55 years old with education levels ranging from high school diploma to PhD. All of them had in common at least 2 years of day-to-day experience with computers (read familiarity with Windows and MS Office for the most part). Only one had a background in Engineering/Computer Science. > Why not make the first-time wizard for KDE ask "Do you want single-click > or double-click"? That would be the ideal solution.
