Just bought Bmax and will try it out tonight, but from the documentation it appears only three button mice are supported in Bmax, as in earlier versions? Is this true? I realise Mark is the busiest Kiwi in the world, bought a Mac with one button mouse, etc, but any chance of support for the back/forward buttons? I work with these 5 button things and it has become second nature to use the extra buttons, that's all...
