I'm running 10.4.10 on a PowerBook G4 and here's the small question I have: I was playing with things in the Universal Access preference pane. Afterwards, some tabs and options got a highlight ring around them. You can see the ring around "restart," and the tabs below is from Azureus and got a ring around "Pieces," which can actually be moved with arrow keys. Pressing space bar will select the tab, or press the button. I've seen this behavior coming and going in the couple years I used the PowerBook but was never sure where this could be set. Any ideas?
