Good news: there is an alice 2.2 update on the website at
http://www.alice.org/index.php?page=...nload_alice2.2
dated 5 august 2011 which you might need to download: older versions of alice 2.2 (especially the ppc rather than intel version) wouldn't work on lion.
The release notes (at
http://www.alice.org/index.php?page=...notes_8_5_2011 ) describe this improvement and list some of the other new features, including tweaks to gallery and arrays.
Bravo for the Alice Team
uh-oh/hmmm... it runs on 10.6 intel mac and looks good, but just hangs up on the splash screen on my 10.7 Lion intel.
