Answer 1

jQuery Knob uses canvas and Internet explorer 8 does not support the canvas element. http://caniuse.com/#search=canvas .

EDIT: You could try adding a polyfill for IE8, https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills#canvas . But I don't know if any of them is compatible with jQuery knob.

EDIT 2: http://code.google.com/p/explorercanvas/ might do the tric, Jquery Knob not working in IE 8.
