Version: (using KDE KDE 3.5.5) When clicking "Show" on the top form on this page (after setting back the "From" date) it is supposed to show a graph of the price variations. Works in firefox, not in konqueror. A working combo on the page is to choose copper and to change the "from" year from 2007 to 1998
This web requires registration, I've used kdetest/kdetest. The page has been moved to https://secure.lme.com/Data/community/Dataprices_PriceGraphs.aspx The good news is that it works for me in kde4 trunk 20080430.
And it works on 3.5.9 too :-)
