I'm running sun java jre 1.5.0_01, on Fedora Core 3, 2.6.10-1.770_FC3 kernel. I noticed you're running KDE. I'm running gnome. I don't know it that makes a difference or not. Oh yeah, firefox 1.0.1.
Sorry, I just looked at the image you had posted, and it does look like you're missing a drop box. I have three, then a button that says "go", then another drop box. It's this last, fourth, drop box that does the settings.
The settings are a little funny for some reason. In the charts window click on the rightmost dropdown box, then select what would be at the bottom of the list. That is really the settings menu. This opens up a configuration box where you can change the background to something other than black, so you can see the black letters in the dropdown boxes.
