you may want to go into /etc/x11/xf86config and see if the keyboard listed at all resembles the type you have. You may want to change what keyboard you have. I suspect that is the issue.
Anyone know what to do about this? Using Mozilla 1.6-5 and tabbed browsing. Focus never seems to be where it seems it should. For instance, click on one tab and press space or pgup/pgdown and nothing happens. Click on another tab and _that_ was the one that scrolled. Don't remember it always being like this but maybe I'm just losing patience and noticing it more.
