Not sure what you see? I switch ocular on, button turns white. I add crosshair, two buttons are white (ocular+cross). I switch to Telrad, Telrad circles are bright, ocular circle is dark, crosshair button hidden. Same with sensor box. Tool button is bright only when options dialog shown. (0.15.0, Win7/NVidia)
