Aside from Stephan's question about selecting, I also wonder how much trouble it is worth to be nonstandard. What you are proposing is similar to the Dvorak vs Qwerty differences. Also, what if somehow it was found that there was a huge advantage to reversing the numbers on an analog clock (12 at the bottom, 3 on the left, 6 at the top...) -- would you be willing to switch? I'm not, and I know a great many other people out there aren't, either. Habit and standardization are a _huge_ things to consider. Single clicks abound in Windows, Mac, Linux, Syllable, SkyOS, TriangleOS, and on and on. As an RSI sufferer and proponent of things which aid in RSI prevention, I'm all for looking for ways to make things better in this way, but this isn't one of them for across-the-board helps or even an option in the Mouse preferences. However, I'm also of the opinion that getting UniversalScroller to work under Haiku is a good thing, too. :) --Jon
