My brother-in-law uses Panther on his iMac and he is curious to know if up and down scroll arrows can be displayed at both the top and bottom part of windows. I believe that should be possible, but does bringing it about involve something other than going into System Preferences and changing settings? Once done, will it remain that way for all applications? I entered "double-arrow scroll bars" in the search box and it did not come up with any matches. Thanks for helping out.
