See attachment. Icon1 is untouched and icon2 shows the icon when hovered over with the mouse. There is a difference of colors, but there is no further visual difference between hovering and clicking. KDE3 used to have an option of seeing the icon as if it were a pressed button. Does this explanation make it any clearer?
Peter, I am at the university at the moment so the rest of my reply will have to wait until tommorow, but until then _please_ make KDE 3 screenshots of the different icon states. The devs already know what KDE 4 icons look like, but to get the same behaviour as KDE 3 I need KDE 3 screenshots.
Thanks! Sorry for the delays, this is a tough wek for me.
