Hm... I could see them. Needed to allow 'ActiveX controls' (don't ask what they are, I'm quoting a pop up here
) to run. In my Windws XP, there is a box to check under Internet Options / Security - Internet / Custom - 'Download Signed ActiveX Controls' set to 'Prompt'.
The last bit showing a bit of pearl grading was fun.
Wish they showed more diverse pearls there...
