I wanted to use mouse-1 single click to do all i want in speedbar instead of use mouse-2 ( scroll button ) click. I couldn't find an easy way so I edited dframe.el and swapped down-mouse-1 event and mouse-2 event. Now I got exactly what I want but the problem is that everytime i move the mouse in speedbar, i always get some highlight as if i am trying to copy something. Is there anyway to get around this or is there a way to solve this correctly   ? Thanks,
