I can only add that it works as advertised (i.e. the pdf is displayed  
inside the window) *without* AR. Please note that AR does screw up  
the OS a lot and it is quite tedious to restore it (if possible at  
all). I'm not quite willing to mess up my system with AR as I intend  
to work on that machine, so if anyone can shed some light as of what  
exactly AR breaks there, it would be nice. My guess would be that  
removing the AR plugin should restore the correct behavior  
(untested). Note that Adobe's un-installer doesn't uninstall the  
plugin and effectively breaks PDF bindings.

Cheers,
Simon
