Flash inconsistency 9.10

[Nigel Ridley]

Running 9.10 from a fresh install.

The page at:
http://www.rapala.com/how2tv/ loads OK and the intro flash movie plays OK. There is a few icons 
under the player window to choose a different lure. There is also an icon to choose from a 
complete list. There should be a slider bar under the visible icons which allows you to see and 
choose other icons.

Here's the annoying bit. Firefox (3.6) and Opera will not show anything in the pop-up window 
(after clicking on the 'Video Playlist' icon/button) which should show a list of choices. The 
slider bar under the icons doesn't show.
However in Konqueror everything works as expected. What gives? I have no problem with any other 
Flash videos.

Any ideas?
