Not having that problem here. But you might want to look into using the following for charts: www.quotetracker.com It's free and it's good.
solved via customer chat, by going into java from control pannel of windows, and deleting old java files
I, too, have IB, but how do you get ES and YM charts on quotetracker? What are the symbols? Sorry, I know it's a newbie question.
