Hello here,
I have designed the following two pages that embed a PDF file and a music Sibelius file respectively:

http://www.musicianspage.com/Apdf.html
http://www.musicianspage.com/Asibelius.html

They work great on Firefox latest version on both Mac and PC and on Safari on Mac. They don't display anything on IE 7 on PC. Any idea? The PC where I am testing displays them correctly on Firefox so I presume both needed plugins are installed correctly...

Thank you in advance for any thoughts.

Best,
Fab.
