After page loading is complete (watch the progress bar), SPAN should have green background

Try to keep mouse out of the SPAN area when it's still loading!

What happens:

• SPAN gets background image through CSS ( background: url(delay.php?seconds=3) )
• Response header is delayed for 3 seconds on purpose
• Opera fails to update background when it arrives
• Hovering SPAN or switching tabs will fix background redraw issue
