Update:

I think I know what happened. The web site removed those extra bits that can show up when right clicking, but the cache has been left behind. A bug in ie9? I assume that the ie9 team are aware of this by now, so won't bother with sending in feedback.

end update.

 

I dragged a web site to the task bar and at first it had icons, but now the graphics or icons have gone missing.

here, a picture shows the problem.
