RAW Files Viewing & Not Viewing in Same Version of Bridge

Hi

I have Adobe Photoshop CS3 on my computer at home and in school each with Adobe Bridge (both bought at the same time so same version).

My computer at home allows me to view Raw Nikon NEF files from my Nikon D90 and Nikon Coolpix P6000 cameras in Adobe Bridge.

My computer at school does not allow me to view these files in Adobe Bridge, only displaying them as icons.

Also, the clarity slider on the basic tab of Camera Raw is present on my computer at home, but not on my computer at school.

Any solutions / explanations to this would be gratefully received.

Many thanks

Carl
