If you see a pink ball inside a black square to the right,
the Chime plugin is installed. If the ball turns green (and
gets smaller) when you click the
link "Small & Green" (not here, at the right), your installation should work

(Clicking the gray X button marked "Large & Pink"
should restore the pink color and larger size.)
If there is NO pink ball, or NO black square, or it does NOT change when you click "Small & Green", please click here for free browser upgrade and troubleshooting help!
