A brief tech support update from our friends at CAS:
On July 20, 2011, Apple Inc. released new versions of their desktop operating system, Mac OS X Lion (version 10.7), and their Internet browser, Safari (version 5.1). Currently, Safari 5.1 is unable to run Java-based applications like the SciFinder structure drawing editor.
This problem is not restricted to SciFinder.
Customers who have upgraded to Safari 5.1 and wish to draw and search structures or reactions in SciFinder should either use Firefox or a previous Safari version until this browser problem is addressed by Apple.
Mac OS X Lion is the first Apple OS upgrade to ship without a built-in Java runtime extension (JRE). SciFinder users who have upgraded to Mac OS X Lion can download the latest Java JRE from the Apple website at http://support.apple.com/kb/DL1421. Users can validate their Java installation by checking this website: http://javatester.org/version.html.
